This lesson by Sang Lee is a great one teaching transition swing path but even great Gary Edwin does not explain well. This is the key of RSS, maintaining shape, back stroke plane is on-plane with left arm but transition is right arm becomes plane arm and slightly over the top of left arm plane, like you said right arm feels like trying to fold the left arm and casting over the plane. This is called hand over the top inside (HOTT- inside) and many top players swing like this. John Rahm and many others including great Fuzzy Zoeller at 66 video here, kzbin.info/www/bejne/qabIZoSGhsuEfbMsi=JudeiodJNdxiqX1C Downswing transition is predominantly right arm swinging slightly over the top of the folding left arm but still slightly inside of the target line but lower body brace and rotate so swing becomes In-to- In. Actually slight out-to-in swing is still fine with little power fade. I am enjoying your channel and you guys swing has improved a lot and also teaching but key is this; trans ion plane is slight over the top of back swing left arm plane but still slightly inside of target line with powerful right arm sling. Cheers.
