re: How do you know when it’s time for a new driver?

I have a G which is why I’m asking. I cant say I haven’t had any issues at all, but the head has been fine. My shaft kinda exploded during a weekend golf trip, but it was sent back to the factory and they said it was a defect in the shaft. They replaced it for me. I also habe the G 3 and 5Ws. No issue with those either.
