Thanks Zef! Sounds like the L/XL aircore should work for my size. I can start out with an XL sport skin that will work with lighter undergarments for relatively warmer water. Maybe a 2XL tech or bullet skin for the colder temps and more layers.
I have the 2xl/3xl fusion bullet with a 2xl/3xl thermal fusion undergarment.
The only thing I don't like about my setup is that the the undergarment and the neoprene outer skin feel too long/saggy in the crotch area. I have roughly a 32 inch inseam. It is worse when the neoprene skin is wet as it feels like it sags. If I needed to replace my skin I would buy the L/XL version. I have only used my thermal fusion a couple of times because I find it just too warm unless the water temp is 3c or below.
