after 4 sessions i think i "broke in" the Rxton 7 (37°) sponge and now it is unfortunately too soft for my usual forehand play. If i dont pay very good attention i will hit through the sponge easily and feel the ball hitting through the sponge and onto the blade. The spin is still there and if i pay attention i can try to just brush and simply accelerate the ball only with the sponge before the ball hits through, but it would definitely need a change of technique which i am not willing to perform for simply "playing the ball once more onto the table" kind of game tactic.
If it was just that, i would say "ok, it is the feeling. i can get used to it" and the obvious answer is to try the other hardnesses of Rxton 7 (got 39° and 40° already here, but only in black, so i cant use it on the spare blade that i just used to test it on). i played against a more seasoned player and he had issues when i concentrated on only slow loops and quite a few balls were blocked out by him when i did that, but in the end i lost. That's ok. Nothing to do with this rubber, because he is simply more consistent and i can not trouble him with "more consistency" with this rubber.
Then i played this pusher/smasher. I got a 40/60 track record against him. He also had issues when i brushed spinny, but i lost a 5 set game against him. I challenged him to a rematch (best of 3) and simply without warming up with it i took the blade with the LAC and beat him 2 to 1. What i could not do as good is close or over the table brush looping, but when we went into a pushing "rally" i could nearly at will loop powerfully and win the point quite often.
EJ'ing is a hell of a drug =/
