Today I ordered a rubber for the backhand - Nittaku Fastarc G1 in the maximum thickness. For two weeks I tried to play with two Jupiter 3. After the worn out Vega Pro about Jupiter 3 on fresh rubber glue and after boosting, I played perfectly. Yes, not the speed, but by playing actively, you could get the result, plus very control blocks and a short game gave the result. Two weeks have passed, the speed is still there, but the elastic feeling is gone, you can play, but it's hard. All the same, the backhand requires a more elastic rubber with a good grip. Waiting for Fastarc...
