Practice with callaway diablo edge irons makes perfect. Buy a bucket of balls at the driving range. Take your normal address with a ball on a tee, take the diablo edge irons back about halfway with only your arms, slowly take the club through the hitting area, and then stop after hitting the ball. Make sure that the ball is hit on the sweet spot. Do this several times until you've trained your muscles to hit the ball correctly. Then take your normal swing with callaway edge irons, and you should begin hitting the ball with more authority.
