Matthew,
I prefer the Ross Course at French Lick to the Dye Course, by a rather large margin, despite generally being more of a fan of Dye. The Ross Course has a lot of interesting holes and features and good topography--they used to call it the "Hill" course as opposed to the Valley Links by the resort which was originally done by Tom Bendelow. That one is now only nine holes. It has long par threes and a lot of medium length par fours, which does hurt variety a bit, but the greens are varied and interesting. Personally, I think the course is every bit as good as some of his private gems in the midwest including Inverness and Scioto, with less history. It did host the PGA, I believe in the 1920's.
The Dye Course is in a spectacular setting, but for the life of me I can't figure out why Dye built these ribbons of fairway that are exceedingly narrow. I think I might have hit one of them in 27 holes played. Quite a few of my drives were very playable from off the fairways so its not entirely a critique of playability, but I didn't see much strategy in 20-25 yard wide fairways other than hit and hope. The overload of bunkers in spots to me also took away from the beautiful natural scenery--it made it look very busy. I think others have made that criticism of Whistling Straits although I found this course to be more jarring. Given ten more rounds with price not factored, I'd play 8 or 9 at the Ross.
