M-wave is better, and I really like Fluffy Muffin, if its in.
Westwater is best below 6000. Little D is prime near 4500. Count is right on with Sock. Bowling Alley is my favorite play, but I like it really low. 2500 is sick. Last Chance is best below 4000. Plenty of other small spots, but again, you do the run as a whole, and the play isn't as good as the park and play spots.
It is totally fun to paddle westwater in a day. I've even done back to back day trips, and its fine. Camping on the river is nice, but not mandatory.
