you can use SpinArt on BH. Its almost like Tenergy, a very hard rubber, as much if not more spin than Tenergy, and slightly slower with more control. really excellent everywhere, anyway just my two yen advice. only on flat shots (= smash) you may feel some difference of power with Tenergy, but for me, it really makes a (small) difference only with FH as such situations are scarce with BH and you may prefer to finish such balls with FH- but i do very much like to smash with my BH, its my "special"...
disclosure: i play with Korbel + T80 1.9 (FH) + Spinart 1.9 (BH) and have been using Spinart for at least 8 years. but i have to admit only recently i am doing "ok" with my BH. so maybe i was slowed in my progression for a long time using that rubber ?
