Hi Ben,
Moving to USGA Spec greens may (or may not) be the right move for the club, but I get a little nervous when I hear these scenarios because this type of renovation there is a chance of losing the essence of course and its original design features. It's true that some of the older courses do need to be renovated (e.g. perhaps the greens were to small for the amount of play they now received), but any significant change needs to be entered into with great planning and care. I hope that the course owner is hiring a qualified and caring GCA to advise him/her, and that, should they proceed to carry out any changes, they are done respecting the spirit and strategy of the course.
I am sure you know that there are good tools available now to map the existing contours of a green so they can be replicated, so that can be done. My tendency is to want to do less rather than more considering a renovation of a classic, but only those with all the information can make the decision as to what is best for the club, course and business.
