Sorry for the delay.
As Ben points out, all three #2's are pretty good, so there is really no obvious best or worst in my opinion.
UM: There are a couple awkward walks between holes at UM, and the walk from #1 to #2 is definitely one of them. I've always wondered how many first timers go from the 1st green right to the 8th tee. Regardless, after walking around behind the 7th green, you get to the 2nd tee, where all you can see if a wall of rough and the tops of a couple trees in front of you. A first-timer would have absolutely no idea how to manage this blind tee shot. It requires a high draw, or straight ball, with fades unlikely to produce a good result. From the top of the hill, it's around 200 or so into a green you can see, but you can trim that to 150 or so if you can carry it down the hill. With that said, getting down the hill makes the approach shot fairly blind and well uphill again. The holes are not even close to similar, but strategically, it's a bit of the decision you face at #7 of Crystal Downs...a longer approach were you can see the target, or a shorter one that's blind. For my game, this is one of the hardest holes on the course.
RF: A fun hole, as long as you can hit an accurate tee ball. I don't really see the look and feel of Dye--there isn't really much at RF that has the look and feel of Dye in my opinion. The best play is a fairway wood or long iron out onto the right side of the fairway, or the right rough. Left presents a lot of trouble on the approach shot, both via trees and a DEEP bunker that fronts the green from that angle. From the right, it's an uphill shot into a decent green. I see what Ben's saying about the tree on the left, but I'd leave it there.
BH: A nice par 5 with good movement throughout the hole and good bunkering, with two bunkers that pinch the landing zone for the second shot.
I really struggle ranking these three. If there was a gun to my head, I'd probably say the same order as Ben...UM > RF > BH, but it isn't with a great deal of conviction.
