I will be testing this setup with the same blade but with different rubbers on it.

Feel free to ask what you want to know.

Korbel is 96g and rubbers are 69g uncut.
What I did realize already when cutting was that with a steel blade I cut one side in one go and the other side 1,5 while I needed 3x full for the d09c.

I am excited to try it out today. Would you recommend using a sticky rubber protector for these sheets? Or not needed?

Just a few notes before I forget it. I will keep it short.

This combination needs some adjustment time. For the first time ever changing rubbers I am struggeling with a new setup even though the blade is the same one.

So the T19 setup weighs 193g and the d09c setup 183g but when I was playing the T19 setup felt lighter. I will need to weigh it again.

Ok now to the playing characteristics:

Pushing: D09c > T19
T19 very uncontrolled in pushing. I am afraid how it goes out of the rubber.

Fh Topspin against block(static): D09c > T19
D09c just more power when standing correct.
T19 is also controlled but slower. Has a "clicky" sound when the sponge gets activated I think. I also think it has a high arc and lands shorter on the table. I feel like automatically I can place the balls to the wide fh (short) even though I didn't really mean it.

Fh Topspin dynamic when moving around: T19>D09c
Here the rubber shines more. It gives me confidence looping in bad positions as well. But because I am not in position I also didn't go hard on the ball but atleast a spinny active stroke.
This was also the area I wanted to be more consistent.

Blocking: haven't tested properly

Chops: suprisingly good with T19

Serve receive: needs more testing but I felt quite confident with the T19. Nothing dangerous but my flicks landed on the table. Keep in mind these were serves from 1200RC players.

3rd Ball attack:
Both about equal as long as I know where their receive gonna be.

Backhand TS against BS: needs more testing

t19: needs more testing but I didn't feel comfortable with my current technique. I could hit really good ones but the consistency was very bad like 20% but when it landed it was good spin and also decently fast. They struggled blocking.
Basically my problem here is I can't use the topssheet to lift the ball as I normally do with d09c. Here the ball just jumps out without gripping the ball.
I don't know I guess I have to use the sponge more and accelerate into the ball.
Topspins with just topsheet is not possible.
Maybe its good to realize that my technique needs adjustment.
With d09c I also struggled but the consistency was way higher like 50%. It's a drill I neglected a lot in the past months focusing a lot on fh. I think the 20% more comes from the tacky topsheet of the d09c.

Fh Ts against backspin:
T19 feels really nice. I was also super relaxed and used my entire body into the shot. This is something I was gonna practise on the next months. Up until now I was lifting backspin with just my arm. But today I could confidently use my hip rotation forwards.
Sometimes I fell for the same trap as with my bh when I contacted the ball too thin and since I dont have the topsheet of d09c it just dies. Maybe this is also the reason why going into the ball with hips works while I dont needs hips with d09c.

Bh Drives:
Since it's catapulty compared to d09c the ball flys out more. D09c balls are generally slower but if I hit the ball more active with T19 I need the swingpath to be right and need to hit the ball at 1-2 o clock. I think I got away with the d09c covering my weakness. Maybe T19 will force me having a stable swingpath more.

Fh Drives:
Very easy ball gets enough speed I would say T19> d09c


I will add some stuff later once I do more testing. But as you can see some strokes I cant even say this or that one is better. I can clearly see their differences and strengths and weakness.

I def think my spin game will take a huge hit. My passive game will be more active on the other hand. My fh receive will be more controlled. My pushes worse (maybe its a good thing and will force me to play more loops)

If I forgot something pls tell me.

Unleash the beast....Think of it as testing a sports car.... no holding back, see what it can do.

Any long serves in your training games......attack (mind set change..always looking for the long serve to attack)
Any long low balls (we see you like the bouncy ones)...attack (none of this passive shot for them to attack)
Pushing is for chumps...open it up or push long to corners to force your game.

New rubbers, lots of errors...Perfect time to change from passive to offensive. Errors today are winners tommorow.

This is exactly what I would have expected for anyone to change from 09c to any Tenergy. But I think this setup is going to serve you well on the long term. You just need to get used to it.

This will probably take a month to get comfortable to the point you dont have to constantly think about adjusting opposed to 09c. And it will probably take you another month to get fully used to the rubber in all situations.

So dont get too frustrated if you are currently losing matches and rating points. In a few months you will be back at the level you were if not better. Be patient, its about the long term development here.

I have the same experience. I switched my FH rubber from D09C to Helix Platinum M(i play with H now though). D09C felt better in drills and with spinsight meassurements I also can see higher spin ratings in drills. However, in matches, the ball does not land exactly where you expect it all the time. So In matches the regular tensor with softer sponge is much more forgiving and works better for me.

I will go to germany on sunday. Will be playing in swiss format so about 10 games that day.

This friday and maybe saturday training.

Toda I will hit the gym so I should prob take saturday as a rest day off since on monday I will also play league game.

Anyway lots of games to be played in the next day. I am kind of scared though since this setup needs adjustment time I am not used to.

It makes me think about timing of the ball more which I wasn't thinking about playing with d09c. Since even at the last second I could just a different pace and make the topsheet to the lifting work.

With T19 it feels like I have to decide my stroke before and it is not forgiving if I hit the ball too early since I cant use the topsheet to lift the ball. So I have to wait for the ball to come into me otherwise its an error.

I am currently in a love and hate relationship when it comes to hybrid vs tensor topsheet.
On the one hand I like it when it grips the ball. On the other hand it was hard to work with the output it was producing. This also explains why I am reluctant in match play when it comes to trusting in my shots in suboptimal situations.

Season will be over end of march. I guess I can just use this time to get better with this setup. I just need to be sure about going the tensor t19 route or go to a softer but hybrid rubbers. I think I need to give this rubber a longer adjustment period.

Anyone knows the approx durability of these rubbers? Also why does this setup feel lighter even though it weighs 10g more? 193g vs 183g. It can't be about headheaviness since the wood is the same even the handle is the same.

Maybe the wood weighs different idk. I am really suprised about that fact other than that I am quite comfortable with 190-205g blades.

Tomorrow I will test further!

Obviously the blades are of different weights (it's interesting that you didn't weigh the blades without the rubbers). T19 is definitely much lighter than D09c, especially on an oversized head blade like the Korbel, and because most weight is felt in head heaviness more than total weight, the racket might feel lighter with T19 even if objectively heavier.

I am not sure why you often post questions you really should answer yourself (no one online can weigh the blades if you haven't done it).

T19 should last you longer than the D09c. I do not really follow what you mean about one of your setups being heavier than the other. D09c has much harder sponge so it should be more heavy than T19. Also Korbel has a little bit larger head size than normal, which means more rubber and more weight than a regular blade.

Why should it last longer?

Yeah I didn't want to reglue both d09c just to weigh the blade. I will do that once I have to change both rubbers.
Since it's a bty blade someone said the blade variance is just a few g. But both setups vary by 10g. So I doubt the other korbel has to be heavier than 10g if t19 is lighter.
All I remember was t19 uncut was 69g

So we will not know about that part. Not that important imo.

This is so untrue, I have had blades vary by almost 20g which I didn't care about when I was younger and newer to the sport but which I am sensitive to now. People need to be careful when giving misinformation, you need to ask for weight upfront to avoid such issues.

From butterfly? The one I got is at 96g now I just realize how heavy that actually is. For some reason I thought its 86g and perfectly fine.

Interesting I think this is the heaviest blade I played with so far. My long is 94g. My other Korbel must be closer to 80 but that would be a huge a variance. Anyway I can't find that out for now. That has to wait.

I still find it hard to compare two similiar setups because It's difficult to tell am I playing worse because of the setup or because I got tired? Did I play better because I switched the blade once I got used to the Drill?

Also some really weird things happen where if I start the drill with the t19 and then play with d09c I perform really well with the d09c.
It's like the t19 setup giving me the warmup needes to play better with the harder setup.

This phenomenon also happened a year ago when I played my very old blade with rubbers like r48 and hexer. I could instantly start looping it was slow and low quality but I could loop from the get go.
Where as when I started with the d09c setup I couldn't loop for the first 15min with consistency I just had no feeling. So basically I had more succes warming up with the slow blade for 1-2min then change and immediatly could loop with the d09c setup.
I did get the same vibe now aswell. But I don’t want to interpret too much into this too early. My brother said he will feed me multiballs tomorrow so I get to practise vs more balls atleast.

Yes, from Butterfly. I have Innerforce T5000, one 83g, another 100g. When they made Mazunov or when I bought Korbels, they were all over the place as well.

So the T19 setup weighs 193g and the d09c setup 183g but when I was playing the T19 setup felt lighter. I will need to weigh it again.
Boi oh boi, can I tell you a lot about T19 -- I have gone back and forth with it on my forehand but have always come back, because there is nothing like it.

Positives:
Overall, T19 is the spinniest rubber I know -- it doesn't reach max spin of Dignics or Hurricane rubbers, but the ease and consistency of spin creation on all types of shots is unparalleled. I also tried rubbers that are as good at ease of spin creation (R45/R47, Vega X, MX-P/S and tens of other rubbers), but the spin of T19 is far above them. That's probably because T05 was already a very spinny rubber, and T19 is a T05 modification with ton of dwell, which widens the window for spinning the ball, multiplied by the strong catapult of Tenergy = you get tons of consistent, heavy, and fast spin.
T19 excells at low-to-medium effort type of shots, where you play relaxed. The spin is always more than it looks and the ball dives sharply on the opponent's side.
Whenever I switched from T19 on my FH to gain more power with harder rubbers, I often hesitated to attack whereas with T19 I attacked every ball, as I knew it would reliably be laced with spin, thus hard to counter. And it also made my opponents play weaker than they normally do because T19 made them play on the back foot and react, which put them out of comfort zone. Also, T19 often made the opponent's underestimate the amount of spin (and speed, it's Tenergy after all) coming their way after a compact stroke.
Serving is also excellent and effortless, nothing to add here.

Negatives:
Where T19 sucks, is pretty much anything that doesn't involv spin creation.
- Pushes are bad, as the ball sits too long in the rubber. You wanna have your pushes/cuts quick, but instead they're of long and bouncy with T19.
- T19 blocks are bad -- I even prefer T05 blocking, since they are more direct, less curvy, and the ball doesn't sit in the rubber. You need to follow-up balls with an arm movement on blocks, or they will be not as dangerous or stable -- it's not a good sign if you need to spend so much effort and focus on blocking.
- Powerful/flat shots aren't great either -- when you try to engage the sponge on powerful shots, you don't necessarily benefit as with the harder rubbers -- the risk and effort you invest sometimes isn't worth it. The ball dwells for too long, which helps the opponents prepare better for counterattacks.

T19 is hard to compare against D09C, I would say the difference in hardness feels even more than the 8 degrees on paper. I can only name one similarity between them - solid spin.
The durability of any Dignics rubber is better than of any Tenergy rubber. However, I would say D09C is the least durable Dignics, and Tenergy 19 is the most durable Tenergy. Thus I normally encountered 4 months of play time for Dignics 09c and about 3 months for Tenergy 19.
The weight is usually about 50-51g for D09C and 46-47g for T19 on Viscaria/FZD.

Some of these are ultimately individual. I know someone who took T19 over T05 on forehand because he prefers to smash with T19 and blocks better with it on forehand (he is a heavy spin player in general). Not what you would think would happen, but dwell helps some people play flat strokes better.

Oh yes sure, I think there isn't even a final say in whether T05 or T19 is faster or has a higher arc :) The division is surprisingly even, which proves the point that it's all individual.

Wow, that is a heavy blade. This will impact your racket speed.

This is interesting, I get my blades to a weight. In future ask for a certain weight range when buying blades.

When I change setup, I leave my old setup in its bag and forget about it. Jumping between just slows your adaption down.

Oh yes sure, I think there isn't even a final say in whether T05 or T19 is faster or has a higher arc :) The division is surprisingly even, which proves the point that it's all individual.
SImple terms, the T19 the ball dwells longer. If you like this then it will seem faster in your hand, if you don't then the T05 will seem faster.
