I've been trying to figure this out for a few years. I bought my driver in '09 (Nike SQ SUMO 5000, 13* loft) and got immediate results. I was hitting it dead straight and as far as I'd ever hit a golf ball. Then the next year, something happened and ever since I've been unable to hit the club right. I've literally only hit 2 or 3 good drives since then. I have a bad slice and almost all of my drives barely make it off the ground, obviously limiting my distance. With the loft being so high, I have no idea how or why that happens. Any suggestions?
