If you are looking at the classic fun series, definitely the fun. I'm 5'6", ~140 lbs (depending on the week), and by the time 3 hrs is up I was in pain. On the other hand, I just looked and tried the redesigned fun (2007 and up), and the Fun is waay too big. I'm all for comfy, but I felt like I was "swimming" (for lack of a better term) in the thing. Disclaimer, I'm a newbie, but thought I should tell you my personal experience considering the similar weight class. Good luck.
