I can do the same thing with the pendulum, it just won't have the same amount of power because there is less mass with just the forearm than with the whole arm.
Now, to your "panties" comments..... if you re-read all the posts, you will find that Lee and I both agree that the elbow should not drop before contact. The main place we disagree with is after contact. I have repeatedly said both work, but the pendulum has less that can go wrong. Lee adamantly states that no drop after contact is wrong and detrimental to the shot. Now, which one of us has their panties in a bunch?? Also, by mentioning Nick and his style, are you actually saying that it really doesn't matter how any one teaches how to stroke the ball? Just toss the cue at the cb, and learn to do it in a straight line and you are fine? I can't believe you would even mention that after all your other posts on various aspects of the game!
