It seems to me that when the clubhead is in balance....all is right with the world.
I think we spend so little time with the weight of the clubhead that balance is just a strength move.
Ernest Jones', Swing the Clubhead..... what a great concept
Toolish's answer concerning Rhythm is most certainly a very solid way to work on feel and balance.........if you know what Rhythm is, that is.
Overrated? I don't think so. Under-investigated? I'm sure of it!
Hold your finish for 5-7 seconds with your arms hanging at your sides kind of swinging a little. Look back in your mind and see/feel if you felt this way through the whole swing, ie, relaxed, no tension, free wheeling!
Three good reasons for holding your finish for 5-7 seconds.....
1. It is a place we need to know so the the force of the swing can be absorbed back into the body and then down into the earth.
2. It is a place we need to have for a time of reflection/internalizing whatever it is we are working on.
3. It is a place we need to have even if you MISS THE BALL completely.........'cause if you stay there for 5-7 seconds, everyone on the driving range thinks you hit it a long way!
Balance? You bet....it's an essential, but, it is in the clubhead where the secret lies.......imho
