whats up josh. we were up on the nf and ran cake, icing and the 12'er. flow was around 750. just my speculation that you could run it down to about 400 or so. obviously the less the water the more abuse. my opinion is that unless you were going to run the punchbowls and the nf it is not worth going. we took the mtn bikes so it made it better, but it is along way in on a 4x4 rd to just run the nf. the camping and scenery is awesome up there and the water is not to cold.
if you are just going to run the punchbowls, go through CB and up scofield pass. you may have to hike down less than a mile but the road is ALOT better than coming from marble.
