Query: thumb action is awkward

I love trackballs, and tried the corded version of this one because my hand fit it well. But I found that I cannot get used to having the trackball under my thumb -- it's excruciatingly awkward. Obviously YMMV -- many reviewers here like it.Plus having used Kensington trackballs for a long time, I find that this ball is too small and does not roll as smoothly as I'm accustomed to. Unfortunately Kensington's current main model has other problems, which I've reviewed there. And the new Logitech which has the ball in the right place only comes cordless, which I'd rather not have to deal with.Edward-- I see the brevity of truth. --
