There is the ethical question here in the USA is about posting scores with older equipment. The USGA still believes every round is sacred and must be posted.[size=78%] I realize those of you in the UK do not post casual rounds; this is an ideal time to have fun with retro equipment. But here in the US, the handicap Chairman may have issues with inflating ones handicap using lower performing equipment only to revert back to modern stuff for Competitions. Is it true that US hickory golfers have two separate handicaps for steel and graphite versus hickory?[/size]
[size=78%]The answer of course is to only post scores from competitive rounds but I don’t see that happening anytime soon![/size]
One thing that I find strange is that the hickory equipment is not conforming per the USGA. I.e. even if I wanted to do it, I couldn't sign up for a State Am qualifier and play the round with the same equipment that Bobby Jones won a US Open with 100 years prior.
I don't know the details with classic equipment, but my guess is that a lot of it would also not be conforming for various reasons. Some maybe because of rules changes, but some because they just aren't actively on the conforming list. For instance, with clubs from the hickory era, the most common reason that they don't conform are the grooves (not perfectly parallel, not lines, too deep, etc).
So it would make sense that you shouldn't post a score if you're using equipment that is non-conforming. I know that some people have asked permission from their State organizations and they've gotten feedback that they shouldn't post scores with antique clubs.
