Thanks for the great photos and the thoughtful analysis. I have to say
that I can't see the 'straightening' in Richard's lead leg that you
I am still having trouble propelling my upper body via legs
and must actively engage my torso in the swing. I can 'sling' the arms
through with my body but I haven't been able to 'sling' my torso. In
that regard I have come to believe that the mental concept one has of the
swing is key and that possibly it would be productive to consider the backswing
as 'strain' and the entire downswing as 'release'.
