I use my index and middle fingers to manipulate the ball (together or alternating scissor-walk like fashion), and ring finger to turn the wheel. Thumb for left click (bottom left button), and ring finger to right click (top right button). The hand doesn’t move at all, with movement all in the fingers.
It freaks out visitors when they try to use it, but it’s a life saver for click intensive workflows. So much so that I would have a second as a backup.
My only complaint for it if I had one is that the scroll wheel can get a little loud with aggressive scrolling in a single direction, like trying to get to the bottom of a page.
I had to reconsider. My thumb joint was grouchy after a few months.
I really like the Kensington Expert mouse for this reason. Expert Mouse Wired Trackball

Ah yeah, there no real place to rest the thumb, but since I use my keyboard like 80% of the time it does not matter too much.
