You could have the trackball on one thumb and the thumb cluster on the other... I have a couple of crooked fingers from breaks that didn't heal completely straight, and I think I'm getting arthritis. So I'm trying to maximize usage of my 'strong' fingers. I should really try a kinesis sometime. Everyone that has one seems to love them...
