I feel your pain. my thumb and hammer have gotten in a few fights as well, but my darn thumb never seems to win. Worst I ever did was while standing on a ladder, holding onto the piece of wood for support, without paying attention i tried to pry a nail out of that piece of wood and had my thumb between the hammer and wood. WHen you do get a chance, like I said before, swing all out because that is how we subconsciously swing the driver and it shows our true swing
