If you're looking for a golf swing cure for flipping, you must first realize there may be deeper rooted causes for your flipping the club through impact. I've been a flipper for over 13 years, and kept looking for bandaide fixes, and never found one until I looked a little deeper and found the issue.
You must get to an impact position with a forward leaning shaft (hands ahead) when you hit the ball, which results in maximum compression, and solidness of contact, creating a boaring, long shot with all your irons.
Sliding Causes Flipping
That means instead of turning through with your body, you slide it towards the target. When you do this, you either cast the club way too early, or you have to flip at impact to even have a chance to hit the golf ball. So to initiate your downswing, don't slide but rotate your body, while retaining your wrist cock.
Flipping Cure In Your Golf Swing
One cure for your flipping is to find a training aid that encourages a "hands ahead" position at impact. One such training aid is the Tour Striker Swing Trainer. This training club is specifically designed to force you to hit the ball with your hands ahead, and a forward leaning shaft. If you don't, the ball will not get airborne.
