Just glued my first sheet of J2 and will test it tonight.

Interesting that the weight of the sheet was within a gram of Bluestar A2. One of the reasons I don't use Bluegrip C is it is too heavy for my preferences.

Just bouncing the ball on the rubber compared to A2, the J2 produces a higher tone sound. Don't really know what to make of that. Nice and grippy, but like A2, it is not sticky at all.

As expected the J2 is harder to activate than Bluestar A2. A2 is much more dynamic in the lower gears, but J2 has the higher speed once activated.

For topspin on block I have to adapt, as it much faster than the O8C on Setup 1 and also much faster than Bluestar A1, which I played earlier.
wait, faster than A1? Donic Bluestar A1? I played for a few minutes with A1 and had to change it as it was absolutely too fast for me and I really didn't like that ... so J2 apparently won't be a good fit for me, unfortunately ...

I have not got mine and glued it up - J1 on FH and J2 on BH (with two thin boost layers which is similar to what I apply to Bluestar and Bluegrip) - will try it tonight on my new ZJK (new era) blade too - can't wait.
looking forward to some thoughts about the ZJK new era blade, too ... ;)

btw - just shortly about Rakzas - currently I am playing with Rakza Z and am thinking about Rakza Z Extra Hard - what are the main differences (except for harder sponge ...). thanks!

As Jk said below, EH is to me a much better FH rubber for me (I am pretty FH dominant) - it has has a little more of everything except for reactivity, which is a little less.

Not my experience - A1 is still faster and more dynamic than J2 I would say - but only based on 3h of playing and J2 still being tight/new.

Short update following 3h club practice and some friendly matches last night. ZJK News era blade and J1/J2.

First of note the frequency of this blade is 1470 or so which is higher than I expected and in the same ball park as my Faster Viscaria's. That having been said, whilst it does feel stiff, it feels less reactive and easier to control than the Boll ALC or Visc I have.

Firstly the rubbers - both felt harder than I expected. I was coming from Bluegrip C2 on FH and the J1 feels much crisper and firmer and also a fair bit faster when you hit it with power. It also felt like the ball quality was better and the arc lower and with more penetration. I won more points on winners through penetration and spin quality than I normally do. That having been said it was a rubber that required more prep and taking the ball earlier seemed to suit it - it was however less forgiving. I would say much closer to Bluestar A1 than Bluegrip C2.
Blocking was excellent and touch game good, but serves required more effort to keep short.

J2 was similar on BH but a little less forgiving and suited my game pretty well - lower arc, high spin than the Bluestar A2 I have been using.

Both rubbers changed through the evening and need more play tonight - it was also seriously humid and hot so all rubbers were under some pressure.

Note - both rubbers were boosted with 2 light layers of Seamoon.

The blade - this is an interesting one. I have been playing with a Boll ZLF and a Maze ALC recently. The Boll is obviously slower, softer and more woody of the three - possibly a little too much so (jury is out) The Maze I love but it's getting old and tough to replace. The ZJK stood out as a stiff blade - nice handle, nice balance and weight (86g) but sharp, quick and responsive (and this is the limba outer, intermediate focused version..)

It took me some adjustment - what I liked;

Classic outer feel - responsive, sharp, good feeling, linear and accurate.

What I was unsure about;

Speed - still pretty fast and requires good technique to control when looping and serving. Am I good enough - it is faster than the Maze and probably similar in outright pace to Visc / Boll, although it feels quite different - it's nothing like a Butterfly blade.

Blade and rubbers together - felt like a pretty good match and similar style - both dynamic, accurate, quick and sharp but with great spin and arc.

This was quite a different feel after my Boll ZLF with Bluegrip C1 and Bluestar A2. A more dangerous and exciting proposition with much more potential, but as always in this case, demanding more from me.

I plan to give this set up a proper testing period before deciding next steps.

I promised another update after my switch to my main blade (W968).

My coach returned from vacation and I had my first session on Monday with the new setup. His words of appreciation were short and his advice very clear.

"Too fast for you old man"

As mentioned I have struggled with consistency on the followup and even in regular exercises which I was able to perform very stable with my old setup, the new setup clearly lacks both - control and consistency.

As mentioned the Js got faster after 10 hours of training and this makes them too fast for me, even on the more controlled W968 (compared to TMXi pro). I certainly could adapt, but it took me so much effort to get stable with my old setup, that it is just not worth the effort. I don't need the additional speed.

So back to Z52.5 on BH and O8C on FH. Maybe once the O8C will be EoL, I might try the C52.5 on VH.

That's it for me and the Js. Have fun.

Thank you for sharing your thoughts on this rubber!
10h to break it in seems a long time to me! Why do you think it gets faster after 10h, is the topsheet losing grip perhaps?

if i read vossi39's remark correctly, only before "breaking in" the bluegrip J-line was having more lower gears which made it more controllable and now these properties are gone.

That would mirror my experiences with many rubbers that might feel slightly more controlled than similar hardness rubbers only to become more lively and then basically not give any control advantage anymore after being played for 10 hours.

For a rubber to be truly more controllable after breaking in it would have to be significantly more controlled or slow than comparable rubbers.

No, the grip is still good and the Js are still controlled in the lower gears. It is more that the catapult effect is now starting stronger and is accelerating even more towards higher gears. I assume it is the sponge that gets more reactive and maybe my strokes are not hard enough to already break-in faster. I'm not a 2000+ USATT player (more in the range of 1700-1900), so my training is maybe not as intensive (e.g. harder topspin vs. topspin is not my routine). My game is more living from spin and placement vs. pure power. I can finish a point, but only when it is clearly a winner (it should never come back, or I'm too slow to recover and make a quality shoot after that).

Also I'm tall with long arms. So I can generate power without needing the additional catapult from the sponge.
