Evan--
Long Cove is not what you would expect considering the designer (Pete Dye) and the period in which it was built (early '80s.) It's doesn't look much like the TPC at Sawgrass at all with very few railroad ties. The course is pretty tight from tree line to tree line (or marsh line in some cases.) The thing that stood out most to me at Long Cove were the greens. They are pretty severe not only back to front tilt but also in internal contouring. The greens make up the real difficulty at Long Cove for the better player as they will most likely not be hitting drivers off many tees. The greens at 2, 3, 8, 14 and 18 are particularly good, although some may think 8 is too severe.
As far as individual holes, the 3rd hole is a mid length par 5 that swings around a water hazard that runs the length of the left side of the hole that dares you to be brave (crazy.) I also liked the short par 4 5th hole even though I know there are some that despise it because of the mound at the front right of the green. I also like the 14th hole that swings around the marsh to an excellent green complex that seems always leave difficult chip shots. This hole may appeal to me more because Pete seemed to always use this particular type of hole as the finisher and used it here when the land gave him a perfect opportunity. The 18th is a really good finisher if only for the great green.
The other issue at Long Cove that I've encountered is that the greens are notoriously firm and the player needs to get accustomed to it. Definitely expect a good shot to take one nice hop at least, similar to what was happening at NGLA this past fall as an example.
I think Tom Doak worked on the crew at Long Cove and may be able to give some further insight into what some of the thought processes were in the design. Long Cove is an excellent course that is worth playing.
