Thanks OB Left,
Thanks KevKarter,
I think the impact alignments are basically sound when I am not striking the ball as in the first video. But even in the first video, the left forearm seems to be where it should be at impact:
I can certainly become more consistent if I can have the left forearm more level at address. And I will try that out some more.
But it doesn't address the biggest stroke waster in my game. The picture above was from the first stroke I posted. And also the worst. I think my computer had a hard time getting that left forearm where it needed to be at impact. But the really big issue for me is: What is the key difference between first and second take? When I have sorted that one out I can start worrying about how to get from 75 strokes to 73 or thereabout.
