Neither 9s are overly difficult. Each provides a reasonable chance at birdie, but getting a little too aggressive on the tee shot or missing your approach in the wrong spot on either can lead to 6X easy enough.
Neither tee shot is very comfortable since both are blind (DR downhill blind and SH uphill blind). Though the width at DR 9 that one can hit it in and be OK is much larger than at SH, I find the DR tee shot more difficult because of the lack of clear aiming points. You have a general idea of what should be good and what shouldn't, but without a caddie (or a Mac, Eric or CJ) in your group, there's no way you can be confident with a line. The tee shot at 9 at SH, while blind, is obvious where you should be hitting it.
The second shot at DR is very easy from a good position and very hard from a bad one. Cleverly placed bunkers along the right side of the fairway should never be in play after a good tee shot, but since they equal death, must be kept in mind after a bad one.
The third shot at DR is very easy with the green essentially forming two large bowls. If you can't get your ball in the right bowl with a wedge in your hand, please get in the cart and drive back to Jack's Shack for a couple of beers. Then inquire about the availability of teaching pros!
The approach to SH is one of the least interesting on the course. JK, you probably are right, C&C could smell that special seasoning and just plunked something down. That being said, there are a lot of places you simply can't miss to.
Overall, SH is a hole you should par a lot and make a few bogies. Not many 3s or 6s. Dismal is a hole that should see a bunch of 4s (birdies) and 5s (pars), but it has the greater potential for big numbers because of the difficult fairway bunkering and the hazard down the left (way, way left), but still there.
Hole is Halved. Sand Hills 1 UP.
