You don't really have to use them all. Realistically on each side I use ~3-4 of the thumb keys consistently and I have the others bound to just things I rarely do. I also completely unbound the outermost row of keys on both sides. i.e. far left and far right. Since I found one of the biggest issues I had that aggravated my issues were stretching the pinky. I also have a Kinesis Advantage 360 pro but I think its better suited for people with bigger hands than me. I do prefer its tenting setup though since its much quicker/easier to use. The Glove80's is a bit more custom but I think I'd have preferred if there was like a good mix of the two.
