I play FZD ALC with boosted H3N 39 commercial on FH and Tenergy19 on BH. I played with unboosted H3N before and could not play well enough. Finally decided I’m already so invested in the Chinese stroke so why not. And all my life I had been running away from Butterfly blades because of the high price tag even though I know they have amazing quality. My friend was in Japan so I said what the heck let’s finally get a Butterfly blade. Also because FZD retired from WTT, I needed something from my favorite player. So people are not exaggerating about boosted vs nonboosted. It really is life changing. I can’t even imagine when I’m ready to move to H3N blue sponge.
As for Tenergy19, I strongly believe it’s better on FH unless you are a very dominant BH player. The effect of holding the ball longer is nice but on the BH you have to be more careful with your paddle angle during topspin rallies. It may overshoot or into the net. Therefore, I think it’s better on FH as you can easily compensate for that holding effect. In addition, it is also the reason I think T19 is not the best on passive blocks. Short touches are very good on both FH and BH. To be honest, I was never a fan of Tenergy05 but after trying my friends Outerforce ZLC with T05, I really enjoyed it on BH. I would say if you don’t want T05 then go D05. I’m planning to change my T19 to D05 soon!
