Floater, I looked at your photos. Looks like a standard shell suit fit to me. You wouldn´t want a shell suit to fit snug like a neoprene one as they don´t stretch. I have a Bare Nex-Gen and ordered a size L. I´m 5'9" but closer to 195 lbs. I could have gone with a L-short if it had been available from where I got it, but I took a chance with the L. I enjoy the suit and have more than 80 dives in it.
