Everyone has different taste. For example to me Quats are way better looking than both Wimbledon 1&2 for sure and the god awful Aussies. To me there's nothing appealing about the GS series other than USO and FO maybe. If Wiimbs released in US as a GR, I don't think most in here would care much and quats would sell faster and wimbs would sit. I'm sorry. I think it's the whole "QS" "limited" thing that's got dudes dropping hundreds over retail for em. At the end of the day nothing trumps the OG CWs of the ATCII. Quats do a great job in capturing OG mystique IMO. I believe had quats been apart of the GS series, you "grand slam boys" would be all over em lol. I remember when quats were on everyone's "must have" list in this thread until they found out they weren't limited. I find that ironic.
Interesting points. I agree with you that in many people's minds, limited supply = must have.
Personally, I love the Aussie Opens and French Opens. I grew up as a huge Agassi fan and these particular GS models do a great job celebrating Agassi, whereas the US Opens and original Wimbledons focus on the tournaments.
