I have never been a participant in online group discussions, but this one has my full attention.
I cannot believe that I wasted so many years of my "golfing life" by trying to make the "toe up" philosophy "work". I recently (and I'm 52 yrs old), decided that enough-is-enough and signed up with GolfTech to have my swing completely analyzed. It is amazing how much better my ball striking has become by keeping the angle "square to arc"!! It takes a lot of practice because of the ingrained "toe up" crap. With the "square to arc", my spine angle is better. My shoulder tilt is better. I may not reach "scatch" status, but that is my quest. I'll let you know how I progress.
