The way I'd play it: the bottom route looks relatively smooth, and when it reaches the middle, would favor the middle-upper passage because I'd take a take flip-jump upwards. That depends on how much jet there is, and how big the map is (although I can judge a tad on size from the size of the colliders in the overview).
My observations from simply viewing this map. Looks relatively simple. Since the upper route looks more tedious than the lower one, it would probably be less used. Not so bad spray-wise. Ought to add a tad bit of scenery, although I wouldn't favor a lot. Maybe some chunklets of rickety fence, or maybe a few desert-like shrubs just as a touch-up.
Edit:
Ok, commenting on this map failed without actually playing it. Bottom route isn't as smooth as I first viewed, but it doesn't bother me. The boulder closest to the middle pillar up top bothers me. Maybe I'll post a pic of what I mean... Unless you are careful, attempting to jump from the uppermost floating boulder to the top route section in the middle pillar is a pain.
