Kalen,
My pattern has been to love my newest courses for a few years, hate then from 5-10 years as I move on to something else style wise, and after about 10-15 years, go back and realize what I was trying to do in most cases was pretty good for what it was......
And frankly, with my newest projects, in some ways, its like re-recording the greatest hits with new musicians, where the ideas seem appropriate.....I know its not politically correct to say, but on the plane last night, after building one of my old favorite concepts - a "catwalk" approach to a green, I sketched out my all time best approach areas. Why not use as many of the best as possible? Ditto backdrops, tee styles, bunker and green complexes, etc.
(I really felt comfy with this on my China projects a few years ago....what's chances anyone would see that course and some of my US stuff, too?)
As you would expect, as I work on the actual topo, not from memory, not all fit as I think they would, and need modification, updating or abandonment.
