(Push) Slice - need help.

It's impossible to diagnose your problem without seeing your swing. All the above suggestions are just speculation. You need to understand what your ball flight is telling you. A push says that the clubface is open in relation to the target line at impact because the ball starts off in the direction the clubface is pointing. The slice says that the clubface is open in relation to the swingpath at impact. If your Pro hasn't explained this he's not doing his job. What you need to do is cure the second fault first. When you do you will either hit it straight, straight left or straight right. This will tell you where the swingpath is, in line, in to out (straight right or out to in (straight left). Since you can't get the ball off the ground when you hood the face (a bad idea!) it's likely, in common with most golfers, your swingpath is out to in.

The pros at the Sunderland Golf Centre are very good, if you feel you need to change, & they've a half price offer on just now.
