I have wasted 2 years of my tennis life trying to master the 2hander and never had any success at all. I guess I am a leftbrain person since I have absolutely no artistical talent at all. That's why I can't control the left part of my body well. Well who am I to argue with God and I'll just have to play the cards I was dealt with. Recently I have switched to the onehander and it just feels much more natural for me. Unbelievably I get more power and control with one hand than two. The only problem is that my shoulder will get sore and tender after a 2hours session using one arm for everything. It seems that even at the pro level the onehanders are more prone to injuries than the two handers. Any suggestions pls?
