I smother hook my drives & trajectory is way too low when I set up stacked, even when I "hang back" & when I move the ball forward etc. The more I move the ball forward the more shut the club-face is when I get to the ball. I am not staying on my back leg too long which would snap the face shut. I play a weak grip & I do not shut the face during the back-swing. I believe it is an issue at the lower part of my downswing or near impact for me so tips on keeping the face square through impact would be appreciated. No it's not the shaft :-)
