Is the Neosport wetsuit as bouyant as others? I have heard they keep the cost low by using thinner neoprene in the legs, so you end up not getting the bouyancy advantage other suits offer.
I have one, actually two, i love them, especially the sleevless, i find them no more or no less bouyant than my Pro-motion suit, and for $100 bucks you cant beat them. I give them a big 2 thumbs up!!
My best advice (depending where you live) would be to rent one and see if you like it before you go for the purchase. Have you used any tri suit before??
I bought a neosport sleeveless last year and used it through my first season. I then bought a QR ultrafull this year and there doesn't appear to be a noticeable difference in buoyancy between the two. I still use the neosport for sprint distances since I can get out of it faster during T1
