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.
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.
