I decided to go with the O'Neill J-type semi dry. Although I wish I had this suit a couple months ago, this suit is warm as heck! hehe! It does allow a little bit of water to get into the suit (hence "semi-dry"), but that little bit of water heats up very quickly!
In testing 2 nights ago in the St. Lawrence river, where the water temperatures were in the low 60s at 24 feet deep (shallow wreck dive), I found that I was very comfortable temperature-wise. When I got out of the water (around 8:30 PM, 70's), I found that when I took my suit off, I was very warm underneath it. This means this suit is not gonna be good once it gets warm out. Luckily I have that taken care of! hehe!
Regarding fit: check online with all the dimensions and weights they list to make sure. I got very lucky, but at first I thought I wasn't: I had no idea about suit lubrication. Completely forgot all that was mentioned during OW classes (they did talk about it once). It was so hard to get on, that I was wondering if this was a good match for me or not! Well, after getting some suit lubricant, I can tell you that it fits amazingly well! I don't have that chest constriction where I feel breathing is hard. I could squat down, and bend in any way that I normally could.
Cons: the suit is a pain to don. Once you figure out all the tricks (roll the legs almost all inside out, except a few inches), then it takes less time to put it on. But once you get the hang of it, it's not so bad considering the warmth it gives you - it's just that internal 5mm farmer John top is funky to get into.
More on this to follow when I dive deeper and colder.
