Recently I switched from a Cobra AMP Cell Offset to a Ping G25 Driver. On the Cobra I was using a Lamkin Crossline Mid-size grip and had a really bad hook. That is why I switched to the G25. I played my first round with the G25 (Ping grip) and found that now I was slicing the ball. I had bought the G25 used from Golfsmith so I was due a free grip, so I had the G25 re-gripped with a Winn Dri-Tac Mid-size, which really feels great. My next two I hit the fairway with 80% of my shots.
Were these two rounds coincidence? Or could a new grip make that much of a difference?
