with your off hand? I'm talking about if you're already established with your strong hand and not starting from a young age like Nadal did. I was thinking this as my off hand tetris skills have become proficient. My high with the right hand is 3.7 million while my left handed high is over half a million. Either way, it's better than most people get and I just started left handed tetris a few weeks ago. The trouble I'm having the most with left handed tennis is the serve, but if you think about it, that's the toughest thing to learn with the natural hand too. Is it possible to outshine the natural hand even if you're already established? I think there is a possibility.
