Last year, I was a high-ball slicer with the driver. Now I'm hitting low hooks with the driver. Many start at my target and then half way there start going left, and they go really left; other start a bit right and turn left sooner; and a few start left and keep going left. When I hit them straight, I'm hitting them better than I ever have, so I'm trying to stay positive but the driver is costing me a lot of strokes right now. Also, I'm hitting my irons really straight right now and hitting the 3W pretty well too. I'm going to try to post some video soon, but until then, anyone have a potential diagnosis?
