Dave,
Not sure I understand the question, but out of 50 golf courses designed, I think I was involved in the site selection process only a few times. And, I recall them going against my recommendations in each case! In other words, there are usually a lot of factors that affect an owner's site selection over pure golf design factors, like land price (or already owning the land!), utilities, ability to own over lease (was a factor at Tangleridge in Grand Prairie, TX) or environmental needs (which the client picked at the Quarry in MN to ease permitting restrictions)
If you were asking in relation to my comment about this group being frazzled about design choices, even if we get to select the site, there are still many, many routing choices. Once settled (or nearly so) then there are feature design choices, then green contouring choices, etc.
When I used to have young associates in the office when first given the chance to design something, they had about 18,000 neat ideas to cram into 18 holes, which usually proved daunting to them in making choices. And, there was the tendency to put the 18 toughest holes they could imagine, rather than 18 good, balanced ones.
Short version: Experience does count for something in golf design, and a few on this board seem to discount that, thinking they could easily envision a golf course if only someone was there to help them out with the technical aspects.
A few could, but most could not! I have seen many amateur routing plans and only a few look decent. Others are so horrible as to...well I don't know, but I know they wouldn't work in reality.
