Subsonic Scott, Can you speak a little about the club face in the MDLT swing? Specifically rotation or rather lack thereof? Thanks.
Basically, the issue for the majority of all golfers is targeting and keeping the target in mind and more finite rather than aimlessly aiming down the middle of the fairway. Club face goes to the target and finishes at the target.
Basic MDLT other than specialty shots is club face to target. If you swing the club head to the target natural club face rotation happens automatically.
What Manuel taught me is if you want to hit a fade you target and set up to start line of ball open club face a very small amount 1 deg/2 deg. neutral grip set club face to where you want the ball to finish but set up and alignment are to where you want the ball to start. The same for draw but vicea versa. This holds true for older traditional equipment persimmon/blades. Where it can controvert is draw bias drivers, large offset irons. Where the club face is targeted is where the ball starts. Most golfers don't really pay attention to the finite need more club face awareness this is where you need to be to shape shots and play to the target. Not so many get weight on front side and finish to the target (ie. those that have to much weight on back foot and don't finish to target-belt buckle at finishing position).
I've referenced this video in the past but always a good reference. This is good MDLT technique. Hands back, upper arms through!
