I'm sure amateurs now need to use clubs with grooves that conform to the rules also
They do, and the rules should be adhered to, but how on earth would anyone check?
Nope. All clubs sold as new should now be conforming to the new rules when bought. But amateurs have until 2024 to ensure the equipment in their bag is conforming .... so if you have a nice stash of old style groove clubs then your good to go for another 10 years, or you have to buy up all the good 2nd hand stock quickly.
