Just got off a wet Deso trip yesterday. Flow jumped from 3000 to 9000 (briefly).
I already have plans to change a few ways I rig my Recretec frame (main frame plus passenger module) on a set of 15' Legend tubes.
Unlike many posters above, I don't like drop bags and was glad to leave them behind when I sold my raft. I'd much rather strap things to a solid floor, wood in my case.
One other point - I see a lot of stuff strapped to the tubes on cats. It seems to meet you have to be careful not to have it too high. I took on some extra stuff plus a rolled up duckie in the back and couldn't clear my oars for shipping.
Just my $0.02.
