Without the benefit of your video, here are some issues to ponder...
Hitters must be wary of deceleration.
Hitters have Transfer Power (6-B-3-0) and
Hitters also have a Finish Swivel (4-D-0).
Do you have it?
The finish swivel may well be the problem.. to me it feels like i'm 'holding it off' with quiet wrists. With shorter irons an angled hinge approaches more a vertical hinge as i understand it so maybe i need to 'feel' a bit more roll when i'm hitting the shorter irons? the ball flight is high with a slight fade, hitting straightish or even a slight draw with the longer clubs.... i've always been a drawer (or probably flipper)when swinging
