I'm 6'7, 255lbs and oddly proportioned. 36 inseam, 36 waist, long arms wide shoulders. I have a bear of a time with suits. My hollis neotek 3xl fits well overall. The pads for knees and elbows aren't in the right location, but fits snugly everywhere. My lighter suits are a bit looser in the middle region and I have just come to accept that. Fins are a big issue for me as well, i have to have open toes fins or my really long toes suffer. This is a bigger issue for open heeled fins than for full foot fins. For BCD the hydros adjusts really well for my proportions. Poodle jackets always fit wrong somewhere and that was in 2xl, the hydros adjust perfect in a 1xl. Hoses are an issue, so my primary got switched to a 40" and will most likely be switched to a 48" with swivel because the 40" halos a bit too much and is just too short for under arm routing. I have a large head and even larger snoz, so mask fit took awhile and more than a few tries to dial in. Head room on boats is less than optimal. I use more air at my size, but I have worked to bring my sac rate into the 6's, so happy about that. (Quitting smoking should make a vast improvement on that as well) 25 years smoking, 2 weeks not smoking so still rough.
