I found out I introduced swaying into my swing. This explains why I could not hit consistently. I'd hit a perfect 4i followed by poor 9i into OB. In the last two range sessions, I kept swaying to minimum and suddenly I am back to my old swing. Things are looking better.
I wonder why it feels so natural to sway? Maybe we feel like it gives us more momentum?
That was one of my major issues as well.
The problem I have now is putting too much spin on the ball. The only good part is the balls land and sit right where I hit them, lately on the fairway and near the greens. I wonder how much distance is being robbed?
I need to experiment with place ball placement, and test different setups.
