I use a Ping G15 driver with 10.5 loft. Originally was having problems pulling the ball and like most golfers was trying to make adjustments to stop it. I was looking into what could be the problem including the length of the shaft and whether or not I should shift to graphite, loft, club head size, weight and basically everything. The problem with the driver really stopped when I changed the grip and what a difference. The Winn Dri-Tac grip ($7) really helped because the size of the grip helped prevent me from rolling the top wrist too quick which was a big cause of the pull. Still using the Ping regular grip which works well for the wedges but if you are having problems with the G15 driver take a look at the grip which can be a real inexpensive solution.
