Not a teacher . . . . but I'd think you are some how disrupting the radius . . . check your head motion . . . up or down? Are you having to shrink up your arms? Some how the club is out too much or you got the face laying on the plane too long.
12 PB, sometimes I do feel that my arms are shrinking up on the down stroke. However, there are times when I feel that I am running out of right arm and I try to get my right shoulder down more into the stroke. Nevertheless, at times, when I add more right shoulder into the stroke, I feel that I have too much right arm and both arms feel like they’re shrinking up on me.
12 PB, I don't have any film of me at this time. I will get new camera equipment after Tax Man delivers my 08 returns. In the mean time, I'll try find someone to film me.
