Believe it or not, I used to swing faster (or at least it seems like I did). And I used to be steeper, which caused a slice. I just brought my hands on an inward path during the backswing, as well as putting the ball more forward in my stance. I don't feel like I'm swinging very hard, honestly. It just feels like my body naturally unwinding from the top of my backswing. In other words, it doesn't feel like I'm doing
too
much. I've tried to swing slower, but I think my tempo over a period of time has been kind of engrained.
