Well, the biggest issue I had was that instead of simply shoving PP #1 "down to China" I would steer PP #1 towards my target which would lead to club head throw away, loss of distance, etc.
But the only way I know how to "hit" a driver is to steer PP #1 out towards my target.
Any other way seems to have me hitting the ball low, right, or simply straight down into the ground.
