....Swinging: take a club in your left hand and, without rotating your hips or trunk, extend it as far back as you can. Now swing the assembly through the imaginary ball and see how much speed you have got and how you are compelled to allow the body to repond to the swinging arm in order for the motion to be completed. Listen for the "swoosh".

Repeat the process but with backswing torso rotation. Do you hear any difference in "swoosh" sound? No, I thought not, so what does that tell you?

Performing the same motions (Hitting) with your right arm only and your experience will be no different.

burner the above tells me why you have been so adament that the turning the hips doesn't add any acceleration...i hear a big "swoosh" difference doing the above with either arm and i'm willing to bet mj does as well...given your stated disdain of tension my guess is that you have slack so that when you turn the hips the torso->shoulder->arm->hand->club don't immediately follow along...
