I don't know why, but it bends the plane line. I can Uncock on Plane but the Left Hand Swivel Roll throws the Clubhead accross the Line.
This is with Straight Line Delivery and Snap Release.
With Circle Delivery and Sweep it works fine but lossed Clubhead Speed. Then it turns into textbook Angle Hinge Paddlewheel Motion of the Right Hand. Softish Impact. It feels like uncocking and rolling in front of my right leg.
