[O.B.Left]

Hmmm, seems trying to turn my left hip violently is clashing with the more deliberate motions of the rest of the body.

I dont know, its a bit of point of contention maybe. Personally, I feel that if the 6-m-1 Downstroke Sequence is a true "Sequence" then by the time it has worked its way to the Shoulders ............the Hips are slowing down and not in a position where they can pull. They are moving, they may still be leading somewhat, temporarily, but their movement is really Motion as opposed to Work.

But, that's just me. My take on Homer's Pivot Train.

If your Hitting and using a Shoulder Throw, Drag Loading you're Four Barrel Hitting. With all of its complexities. Drag then Thrust. Id work on Three Barrel Hitting till you have that mastered, maybe be able to alternate Swinging and Three Barrel hitting before you try Four Barrel Hitting. You need to be able to go back and forth between Drag and Drive Loading , Left Hand Throw vs Right Arm before you can employ a hybrid mix of the two. You need to be able to distinguish the unique identities and feels prior to mixing them together.
