When I play I'll take a couple of practice swings (hits) tracing the planeline (with RF and PP3). I'll watch the direction of the clubhead into impactposition.
Then when I hit the ball I'll abandon the feel of tracing the planeline. Instead I'll hit down on the ball, out in the direction of the clubhead seen in the practice swings.
That's it - is that it?
All kinds of stuff goes wrong sometimes: ie. when I want to hit it too hard and runs out of right arm, or when the feeling of wanting to hit forward gets too big, or when I take the club too far back and turns the hands and suddenly needs to swivel/roll back into impact........etc
But on most days, this is sooooo simple. Just trust it, and hit it long and straight.
