I've updated my Casa Verde course, for anyone interested. I'm hoping to get a second one out in the next few days; it's nearly ready, followed by another one on top of that. The hardest thing is coming up with names for them!
I think the sameness of the TGC courses obviously has to do with the limited number of themes, but I also feel like a lot of the same concepts and techniques are used - everyone seems to want to make everything as narrow as possible so you get these little skinny fairway slivers with a zillion bunkers and greens that have five different tongues and tiers.
Looking at mine; I guess I tend to design on a bit of a larger scale than most and I (admittedly) sometimes repeat myself on certain ideas and formulas... but I also like to think those things are tried and true. I guess I also tried to follow real trends in design, and some of the major ones these days are towards width and minimalism. I wouldn't say that I'm completely minimalist, but I do like to be economical with hazards..... I think most hobbyists will use hazards as a bit of a crutch, so the challenge for me is how can I make interesting holes without depending on those things. Some of my favorite holes I've ever done were bunkerless and waterless.
I think more than anything else, I want a course to look like it could exist in nature, that I would want to play it, that the variety of the holes is sufficiently mixed up so I don't feel like they repeat, and that it isn't too hard for beginners.
