Pat,
I didn't say anything about an "experiment". You read things into what people say that enable you to disagree.
The need for restoration usually comes because the entire hole has been abused. Trees take away lines of play, bunkers have changed, fairway width has been lost,greens often have shrunk, rough buffers have emerged around bunkers, etc.
I do believe that one way to prioritize a restoration--the title of the thread--- is to show what it will look like when complete.
I think the original posting spoke to a limited budget, so I believe showing what the end result can be may lead to more money being allocated. If you do it in bits and pieces it may take years before people see the benefits and get onboard.
The risk associated with badly executed work exists from the alternative route of doing all the bunkers first, as an example.
In the instance of a big budget I would agree that going like Sherman through Atlanta is okay (no offense intended to our Southern friends).
