It used to be whenever I lost it, thanks to MGS I try to avoid using any that have a noticeable scuff/scratch. The games hard enough without losing distance and accuracy because of a beat up golf ball.
I'm at a point with my swing that I'm not looking to make any major changes but I am looking to add more structure to range sessions beyond aiming at a target and hoping to hit it.
What routine have you implemented that really helped you dial in your game without trying to change your mechanics?
