Last night at the range I really tried to bow my wrists when hitting driver and I think I'm on to something that works for me.
The feeling is bowing the left wrist at the top of the swing. I think this straightens out my left arm and gets more speed through the ball on the down swing.
My irons were ok. Hit quite a few good ones early but ended on kind of a sour note when hitting a 6 iron. Just needed to get back to fundamentals with my grip and hitting in front of the ball.
