Since nobody else mentioned them, I'll chime in. I use versa gripps
basically act as either gloves or straps/hooks depending on how you use the paddle part. Nice thing is that if you wear them loose at the wrist, they are easy to spin around so that the paddle part is on the back of your hand. Here is their site
I use em because i have thumb arthritis from being a software developer too long and too much time at a keyboard. So I don't have crap for grip due to that.
