I'm 6'3 315lbs, i've tried both boats.
I like what fatmanz said.
I prefer the super fun to the mon-star over all. I also prefer river/play vers. playpark play and can run harder rapids more comfortably in the super fun.
I am a bit bigger than most and never stood a chance at a loop with an overthruster on either boat
so i got the brand new, top secret, fat shit, huDge loop, dope props super hero for my phonix monkeys and MONSTER LOOPS!
i could stand to lose a few pounds
