EdZ:
I get the feeling when I'm really compressing the ball. Just snuck away to hit some balls at lunch. I was focusing on something similar. When I hit 1/2 swing punch shots, I can really feel it. When I started getting a bit longer (with my wanting to hit it further) I lose it a bit.
At the course I practice at in Florida (Bloomingdale Golfer's Club), PGA Tour guy Michael Bradley is a frequent practicer. He was there today hitting some balls with is father. He swing is very smooth and he has a very noticeable 'swinging' motion. He really directs his swing with his hands whilst the pivot adds the power to a lagging clubhead!
