This description makes so much sense, very well put! Keeping my wrist straight by tensing up my grip has seemed to be working like you stated above. That rotation part of the video is so true, I totally think of it as spinning the ball around horizontal. Instead of a titled spiral.
One thing I have found myself having trouble with is my shoulders opening when I am pushing off of my brace leg and posting up. My leg is tensing up but my shoulders and torso just whip around. Do you think I should actively try to stiffen up my entire upper body when the disc is around the power pocket?
Watching that David Wiggins hyzer at the European open makes me think he has to be keeping himself closed and bracing the shoulders/torso so that it doesn't open up to the target. Tensing his body up while swimming away from the target with his off arm? So that the only moving piece left is the arm coming in like a sledgehammer. I can do this movement with something heavy but keeping my shoulders from opening with a disc or just swinging my arms seems so hard
Can't figure out how to embed on my phone...
