Anyway, has any cpen player managed to serve a reverse tomahawk? I'd like to learn it because, frankly, my pendulum and reverse pendulum aren't effective, my opponents return them as if I served a dead ball....

 

Another Q , does the contact point affect what spin can be imparted to the ball? I've tried down, side but it seems like I always get the same spin, I tried for a topspin-sidespin but all of them look like a backspin-medium sidespin serve even if I don't contact the ball at the bottom....  I'd appreciate a lot of help with this... 

 

Thanks a lot in advance
