I agree that if one swings with the eyes closed, that one can 'sense" the weight of the clubhead. However, I don't believe that one can precisely sense the sweetspot.

If a golfer thrusts (or throws) that "'clubhead weight" at the aiming point, without understanding human golf biomechanics, then he should expect shanks and/or all kinds of mishits. One needs to execute the "correct" biomechanical movements during the downswing i) to get the clubshaft to descend down to the ball on-plane and to ensure that the clubshaft at impact has the sole of the club parallel to the ground and touching the ground; ii) to get the clubface to swivel 90 degrees into impact during the release swivel phase (from the 3rd parallel position to impact) so that the clubface is square at the time of ball-clubface separation and iii) to get forward shaft lean at impact (FLW and bent right wrist). That is what "educated hands" is all about - moving the clubshaft and clubface "correctly" in space to achieve those goals. That's also what TGM is all about - precise biomechanics, precise mechanics, precise physics and precise geometry.
