I personally have tried this with little success... Its just a feel thing I guess you could say. If it dont feel right then dont keep doing it. I may have one of the free"ist armswings in the game but its all about gravity doing the work and not necessarily just taking muscle out of play at the beginning.
Im not saying try it, Im just saying it works for some and dont for some. You see some players drift 15 boards in their approach and Im thinking WTF. But they do it the same, and it works for them!
Just on a side not, I just recently moved up from 15lb. to 16lb. and that has fixed me turning the ball early,etc. I think the extra pound has made me really wait on the ball in my backswing! Not many people though will agree with what I said, but that helped me. john
