I try to use the iPhone when possible at the range. I think it helps a lot.
I've noticed that when I begin my downswing, the club shaft is bending away from the swing direction (as you would expect). However, as the club reaches the lower part of the swing, the club looks to be flexing the opposite and wrong direction?
Is this my swing? i.e applying power too early in the swing? Or perhaps I need a stiffer shaft? I'm sure I'm losing power here.
