Hi-
I'd be interested in what Tyler says. My thoughts are as follows. You have a lot of upper body lunge in your second video side view. See pictures captured below. you also have your hands way behind your trail hip at delivery position. And way past post impact you still have your head down which prevents the right side from getting into impact and in my experience leads to a flip post impact rather than the release you want as a result of the wipe, which would be to have both arms extended, rotated body and club head appearing to the right of your body as the club handle disappears left. So I think you have a transition problem (upper body lunge), a release problem (an incomplete ulner deviation and a failure to get your trail elbow in front of your trail hip) and a post impact problem (your head down for way too long stiffling rotation leading to post impact flip and odd exit
Where to begin? My suggestion is start with release and post impact. As for release I would start with the drill Presetting the Unhinge. I would also pay attention to Tyler's turning his chin in sync with his sternum. This really helps get through the shot, get the right side into the shot and the proper position at the end of the wipe.
I see that Tyler has focused directly on your concern about shanking and I certainly understand that. On the other hand, i understood you to be complaining that the shanks were a result of steps you have taken to improve your release and eliminate early extension, so I focused on aspects of those issues because I still see signs of the problems you were originally trying to deal with.
