Want to try a Tri Suit this year....

Last year before my first sprint tri ever, I went out and bought a nice QR wetsuit, thinking....yay, buoyancy....ahhhh, warmth in that COLD water....only to find out when I went for my first practice open water swim that because I get sooo overheated when I work out (red in the face, sweat like a pig...it's very attractive) I can tolerate some fairly cold water temps with just my swimsuit, and can NOT tolerate being encased in rubber. So glad I had a couple hundred extra bucks laying around for a wetsuit I'll probably never wear. What I ended up doing on race day was just swim in my suit and throw on my bike shorts at T1, worked fine.
However, my goal is to shave some time this year in my transitions, so I am thinking of getting a QR one piece tri suit to wear for the whole race. Before I shell out the $80, I was wondering if anybody else has worn one of these (or another brand) for race day? My only concern is that it will be really wet when I hop on the bike, not sure if this would be an issue at all (thinking chafe, maybe?). At least I had my dry bike shorts to pull over my swimsuit last year, so they were not quite as wet as the tri suit would be. I appreciate any input anyone has.
