we did a thread on this a few weeks ago---cant remember the title of it.
I've done both. Im back to the 2 piece. I wanted to use the Lycra Power as used in the Desoto Power shorts, but didnt like the looks of the desoto one piece (plus everyones got it).
The downside of the fullsuit? I dont really have a belly, but the suit i used pressed on what i do have and if i was already feeling nauseous this didnt help. Cant customize looks, sizes etc. If the top rips the whole thing is ripped. Tougher to pee, not impossible at all, just a little tougher.
Benefits? If you grab it, you got it---meaning its possible to grab your shorts and forget your top. Keeps the sun off the little piece of skin above your waist. You could pull it down, if it got way too hot (this is the reason i went to a fullsuit, but never actually pulled it down midrace."
