"Due to the cost of construction of a USGA spec green, I do feel like if the site is right (sandy to sandy loam) then the building of push ups would be the way to go, no doubt"
Bingo. As a member (or even someone with some authority on a renovation project), I'm not going to disagree with our superintendent who, though very comfortable with the 80 year-old push up greens at the club, thinks that in building a new green the crummy clay soil makes the risk of a push up green too great. Would you try to insist that push up greens be built no matter what the soil is like Patrick?
Also, I've done a bit of archeology on club histories, and it appears that many clubs had significant problems with their greens back when they were built, and OFCC was no different. I got articles from the club magazines back then that talk about how the greens are going to be redone, about how they are going to use new or more layers of stuff, sand, gravel, hummus etc. etc. to try to get them to work better, and other issues with them. So I would not presume that these 80 year-old greens always functioned so well without going back through the history to see.
Interesting that awhile ago there was a thread about how lousy USGA greens were in comparison to push up greens, and now we have one where the value of USGA greens is presumed.
