Whip, with my artificial hip, 11 hip operations, shorter front leg and non-athletic build, I figured I would zero-out the Pivot so I can walk a little better when I'm done with the round and Hitting has really helped. Last week, I shot an 86 having been on line all day but short by 10 or 15 yards using a stiffer shaft in newer Titleist ZB's, and a 77 two weeks earlier. This weekend I'll add two clubs and Hit and get a senior shaft in the clubs after my round unless I am missing something obvious you'd like to mention.

I would have to see your motion on film to asses what your best options are. Realize though that the hit requires some definite pivoting as well although with a preturned hip it can be easier if you'd like u can pm me a YouTube link of your swing if u have one. You can also equally swing from a preturned hip position and only go to top, and swing quite well perhaps better than your hit procedure at the moment not sure.
