I think you will get a hip turn when you do a Shooulder Turn Throw. Don't know whether it's a cause and effect thing though. Could also be partly common causes from the feet.
I never try to fire the Hips to turn the shoulders. I fire the right hip and try to hold the shoulders back. Quite similar to shoulder throw, although I rarely use the sharp initial acceleration. Then I fire the left hip I pull the shoulder and the arm and the club. While I turn the shoulders.
Hi Bernt! Maybe because of all my hip operations, I just cannot consciously trigger all those components or even feel them.
Still, it is really fun to know that I an bump to the left in a variety of ways and watch the swing blur by! I feel like I am doing the "crapsmacker" when I bump left and sidearm toss the right elbow and forearm.
I guess this is just plain (plane) fun!
