Taylormade burner 860 Ti drivers, all illegal?

I take it you didn't win the game then.

I know it is cheating, but to be honest, he would probably hit it at least as well, if not better if he bought a new driver.

Trouble is, there must be loads of people who haven't updated yet, and they do need to be dug out and made to change. Rules are rules after all, even if there is no advantage. Talk to the pro or general manager and see what they can do for the future.

So far I don't think this has occured at my club.
