Hmmm, I hate having to reach around. I have short fat stubby fingers, but, I dunno, I'm really starting to get consistent sub-40 times now. So I guess I'm doing something right. I normally use my pinky, but I quite often use my index finger because I don't trust my pinky strength too much. I've tried to use my ring finger a bit more lately as well, and that's actually gone quite well, but it is very restricted because I have to bring my hand around a bit...
