Doug-
I'll try to help you out here...I've played National twice, and Mid-South once, 2 years ago, when it was called Plantation Golf Club.
National is, by and large, a very difficult track. People in the area seem to hold it in high regard, and it commands a higher green fee than most...
There are some very good holes IMHO (5,10,18) and some bad holes (1 and 2 are poor opening holes...when you play 1, youll see what I mean...they would make a great 16,17 combo, but not 1,2)
It's a decently fun course, though the greens are clearly early Nicklaus (i.e. HUGE elephants buried here and there, tiers that make certain pins absolutely unputtable if you get on the wrong side...) It's generally forgiving off the tee, for a sandhills course...
Mid-South was 2 years ago, so I'm stretching to remember...but from what I do remember, the course took a few holes to get started, but it made interesting use, I thought, of a pond/lake both on the front and back nine. The conditioning was suspect when I played, but again, new ownership, now private, I'd imagine it's better. The layout, other than the few holes that ran around the lake, reminded me of the Carolina club, and almost scream Palmer...its a decent track, and one that I would play again, but in this class, I'd run over to Legacy half the time and play one of these two the other half...
For the $$ it costs to play National, you can play Mid-Pines, cant you?
How bout Tot Hill Farm? Strantz design- from what I hear, less polished than Tobacco - quirky, fun, and if you like TR, then the locals say you'll like Tot Hill too...
