I will make it simple. Your Monstrous Fade is a slice! But its a combination of (1) the hands are ahead of the clubface at impact, and (2) the swingplane has the clubhead traveling outside/in when the ball gets contact. But consider some of the things that I have come across to get things straighten out.
1.Your backswing should be straight back wide with your shoulders and arms. NOT your hands. You know if your doing it right when the toe of the driver is facing the sky and the clubface is verticle when the grip is pointing at the target. DONT TAKE THE BACKSWING BEYOND YOUR MEANS OF FLEXABILITY. Your chest will be forced back and it will effect your swing plane.
2.Understand the importance of a smooth tempo. If you straighten your wrist too early, your clubhead will close up. Hit the ball on the downswing were your hands were during address because that is the only time that the clubhead was square to the target.
3.This is the most important thing for me. PICK A TARGET AND FOCUS ON THAT TARGET ONLY 100%!!!! CHOOSE POINT LIKE A DIVOT, A BLADE OF GRASS, OR SOMETHING EMBEDDED ON THE GROUND THAT IS ALINGED WITH THE TARGET 7 TO 20 INCHES IN FRONT OF THE BALL. When you hit the ball, your goal is to make sure that your clubhead also passes through that point in front of the ball to encourage the clubface has a straight swingplane.
Number 1 and 2 belongs in the driving range. Number 3 is also in the driving range, but exclusively in the golf course. If you think about 1 and 2 on the golf course, then your screwed! LOL!! I say that because 3 is psychological. That is the most powerful tool ON the golf course. Not talent. That is why not too many people can play for money or never transfer their talents to the golf course.
Definition fo a target: A target is NOT the middle of the fairway. The target should be the smallest point that you can find like a tree, distant bunker, or anything beyond the part of the fairway you want to attack. The higher the target the better. That would be a bit more challenging on a links course.
