I took the easy way out: I asked the opinions of very experienced people who were doing the type of diving (extended range, Great Lakes shipwreck diving) I was hoping to do, and then I opened my wallet! Never looked back. No buyer's remorse. (Well, I did have pockets added and a protective zipper installed when I had my original DS zipper replaced after owning my suit for about six years.)
ETA: If I were to make the purchase right now, I would order silicone wrist seals (to go with dry gloves) instead of the neoprene fold-under wrist seals I have on my suit. I've been watching a lot of videos about diving Iceland's Silfra fissure, and water temps there are barely above freezing--much too cold for me for cold-water gloves or three-finger mitts!
