I own an Evo 3 mm, and a Pinnacle 5mm. When you look at an Evo side by side with other neoprene, it looks like a wet towel. It fits nicely, but the neoprene is cheap. My pinnacle cruiser 5mm, on the other hand, is great. It has become my go-to suit. I am a fairly small guy, but I have pretty large shoulders. The Pinnacle fits me like a dream. I love the seal it gives me around the neck, wrists, and ankles. It practically fits like a semi-dry.
My 5mm has also become my year-round suit. My 3mm was great at the time, but I get chilly at depth, or when I'm down for a couple hours scraping a boat hull. Ever since getting my 5 mm, my 3mm has sat in my closet. I have heard complaints that it is too much for Florida, but I took it down to the Keys for a couple days a few weeks ago. I wore my 3mm on the first day, but I got chilled(in 80-82*) water. I wore my 5mm the rest of the dives, and never once felt chilled or overheated.
The nice thing about overdoing insulation a bit is that you can pull the neck open a bit to let water fluch through if you get hot. If you're cold, you can't do anything.
