I have two problems. With my driver I have the ball position lined up with my front foot heel, and aim a bit before the ball so that my club is in alignment with the middle of my stance, the ball being forward. I've changed up my tee height quite a couple of times but I'm still hitting too low on the tee. I either pop the ball right up, or just make terrible contact and slice it. Like I said, I've switched up the tee height numerous times, so I'm figuring I'm dropping my shoulder or something causing me to hit the ball on my downswing. I also might be using too much of my arms. Tips?
Edit:: Today I went back to a course and used my driver. Through the front 9 I was struggling a lot to make clean contact, than I started using more of a shoulder turn and I was making very good contact with my shots. The only problem was consistency as I would slice about 50% of my tee shots. Some slices weren't that bad and some were pretty much out of play. Anybody have any quick tips to help slicing with a driver?
