Hot face drivers | Golf Monthly

What's a killer is up until a month ago my driving (armed with current driver) was the strongest point of my game, I can only think I have changed something in my swing which is now why I can't use my current stick, I can see a lesson being the only way of finding the issue although I have a strange feeling it's because I've slowed my swing down too much for the stiff shaft which would explain why my old driver with a regular shaft may seem like an easy out option
