Jesper:

I tried the 10 finger grip late last year ( I was having a terrible round so figured I'd try something new). I just couldn't get use to it although I was hitting the ball better. Have you tried an Inter-locking grip? The interlocking grip allows me to feel my arms as a unit and I swing a lot better with it.. If you find the 10 finger grip works for you; go with it.
