Being a scratch golfer is impressive, but playing with scratched golf clubs is not. If you don’t wish to take your nicked-up clubs to a pro shop for refinishing, you can repair small scratches yourself, pretty much the same way you’d touch up scratches on your car.
The launch angle of your shot is measured by the initial elevation angle of the ball immediately after impact with the club head. If you launch shots high into the air, you have a high launch angle. There are a number of ways to reduce your launch angle. Some are simple, such as teeing the ball lower or reducing the loft of your driver. Some require a change in your swing that might decrease your distance and/or accuracy.
