Yeah, be careful. Cubing isn't worth messing up your wrists. Just a thought, the creators of the PowerBall (http://www.powerballs.com) claim that their product is good for RSI. I don't know if this is true or not, but I have one and it's a ton of fun to play with! I could see how it might be good for RSI, though. When you get the hang of it (which doesn't take long) it's a pretty smooth motion on your wrist. Good for strengthening your arm muscles, too. You'd be amazed at the workout you get from playing with it.
