I have used T64 for about 6 months. (It was really pricey for me so i used it for a really long time xD)
I used it on my Donic Burn-Off blade on my FH. I didn't really like it because it was too soft, pricey and less spinny.
What i want everyone to know is that it is a good rubber but *** It is not for everyone ***
What i like about this rubber is that it is good on both BH and FH since sometimes i used it on my bh also.
To me, i think all of the tenergy series suits on both BH and FH.
Lets get into the real deal!
It has a low throw angle which makes it easy for you to make errors.
When i first started using it, my pushes would go off the table or into the net.
It takes quite a while for me to adapt to it.
It is really good for people who is dominant BH player. During BH drive, it helps produce a really powerful BH and easy dropshot.
As for serving, due to the soft rubber it requires a really fast brushy movement in order to produce a really spinny serve but you'll get used to it when you use it.
Its nothing to worry about.
*** Really good for BLOCKING but needs skills***
Blocking with this rubber is almost effortless. Yes. Effortless because of the high tension sponge.
FH topspins and loops, when using it for my FH the topspins and loops i had to adjust my technique but after adjusting, the topspins and loops with this rubber is really great as it gives you explosive speed with the help of the high tension sponge.
Sorry if i made it sound like a butterfly advertisement at some point. xD ahahahaha
*** ALSO, i forgot to about the durability part! After 1month of using it, i already felt some lose to its speed and grip.***
Butterfly should have made it a lot more durable since it is really pricey. Im kinda disappointed. :/
I would recommend this rubber for developing intermediate and above.
This rubber would suit people who prefer mid distance play, soft sponge and for someone who prefer explosive speed instead of spin.
