Bandon Dunes, Pacific Dunes...whatever!!! I told you...I am hopped up on pain meds!!!
Regarding Seminole and Achasta, I am trying to answer your question...but you seem to not want it answered. Seminole is WAY better. Better routing, better greens, better bunkering...I could go on. But it is too difficult for me...at least it was the 1 time I've played it thus far. 30 mph winds, 13 stimped greens, wild slopes, bunkers everywhere. It seemed even the good shots I hit didn't work out like I planned. This wasn't "fun", but I am interested to get back out there and try to apply what I've learned about the course to see if I can do better. But the low handicapper would love the course I am sure.
Achasta is pretty good and under-rated I think, but it isn't in the class of Seminole. And frankly, for Seminole I could input TPC Sawgrass as well. Perhaps even Kiawah Ocean (which in my humble opinion is the "best" course I've played). Anyway, back to the Achasta/Seminole comparison. Achasta's routing isn't close to Seminole's. Achasta's variety isn't close to Seminole's. Achasta's greens are boring compared to Seminole's. Achasta has some "odd" holes. But I have fun on it, because no one is ever there...so I seem to get the course all to myself whenever I play it. The greens are more receptive to the golf ball, so scoring is easier. The routing is pretty good at Achasta, but at times the creek that cuts through the course gets redundant redundant and presents the same type of shot time and time again. But again, the course's "fun" factor is there for me and my taste. The mountain setting is particularly stunning in the fall...and like I mentioned no one is ever there...even at that wonderful time of year.
Anyway, that is what I got.
PS...I've seen you've posted more, but I think this touches on your added posts. And you will see this isn't a "punt". I've tried to answer in some detail why Seminole is "better" and why I have more "fun" on Achasta. Also, on my website I make it clear that I am ranking my "favorite" courses rather than the "best" courses I've played. Therefore, I hope this shows I've put some thought into your question prior to this and also shows how important I think the topic is.
PSS...The reason I posted the Oakmont question is that of course it is a great (superior) golf course architecturally. But I really don't think I would find it "fun" given my current handicap. So, again I am trying to provide an answer to your question.
PSSS...did I mentioned I had to take some pain meds?
