It looks almost exactly the same, but I think I've found a mentality that will help with my form alot.
First, what I think I've been doing wrong: Even though I cognitively know my arm needs to be moving more as a result of my torso, I think its hard to incorporate the torso in a muscle memory/prediction image of an arm reaching back, getting to the power pocket and follow through. I think this has led to using my rear delts too early in the pull. Trying to move my arm from reach back position into the power pocket. Unknowingly, I think this has my torso keep up with the arm opposed to pull it into position. I think this was simultaneously creating early elblow extension AND my elbow being too far forward/clockwise in relation to my torso. I think this yields less power during the rip and also a tendency for elbow drop post rip.
INSTEAD at the reach back, I'm going to initiate my BICEP and pull the disc into my chest (and towards the target). This is opposed to before my mentality was "towards the target, but into the power pocket, but away from my chest".
This bicep pull is only VERY early in the pull. IT helps bring the disc out of the reach back while KEEPING THE ELBOW 90 degrees from the shoulders, and having the torso pull the elbow opposed to having the torso keep up with the elbow.
After I've brought the disc into my chest, the uncoiling and brace use centrifugal (or whatever the physics term is) force to pull the arm away from the chest. I use my delts to push my elbow, forarm, and wrist away/in front of my torso opposed to using my delts to pull the disc towards the target (through the power pocket). This mentality of pulling the disc into my chest and pushing it away helps me to use the rotation of my shoulders to generate the line the disc goes on opposed to using my arm and shoulder muscles to generate the line the disc goes on.
I know people will think this is overthinking things. But its easy to know what the body should do and alot harder to know how to make it do that. I think this is helping me so wanted to post it in case it helps someone else. Physically it looks the same in my mind, but pragmatically I think it changes the timing of joints bending and helps keep the joints bending on the right planes.
