I used a 50" driver for a couple of seasons back in the late 1980's or early 1990's. The long shafts definitely give you longer drives but like others have said, you need to practice with them. My main mistake when I started using them was to not be patient enough with my swing. If you try to swing hard you may, like I did, end up getting your hands ahead of the club head and hit a fat slice or nasty push. The other thing I found was when slowing down my tempo, I would sometimes relax my wrists and still hit a slice or push. Use a smooth swing and don't relax your wrists too much and you may find the long shaft is your friend.
