I am sorry; have not been on forums forever. Do not know if appropriate or not. Son now 20! Has moved from Ping to 670G and we are now on silhouettes. Had been with Ping for 10 years on Inset 30s. We have boxes of sets and cartridges. Hit me if interested--I would be happy to ship them to you. I hate to see them just sit here if they may be useful.
