Thanks.
The ball on the Logitech Trackman is just too small, I had one and I agree is is very hard to move well.
The Kensington Trackball has a much bigger ball, I think about 2X the size of the Logitech. It takes a little pratice to get useing it. But once you do you don't want to go back to a mouse. I really do love it and it made a huge change in my hand. I was at the point my hand was hurting all the time, I thought I was going to have to stop playing. I have trackball both at work and home, now I don't have any hand pain, while playing 6+ hours a day.

This is what the HR people at my company make us change to if we tell them we are having Carpal tunnel issues.
