I'm looking at some pretty cold water diving, great lakes, quarries etc. And inherent in those dives are wrecks, I've read a lot of different opinions on which type of suit is more "rugged" and found that neoprene is a bit tougher but its also tougher to patch than trilam. I've also read about the squeeze problems with neoprene that affect buoyancy. My price range is probably below $2000 so that leaves some room but pretty much eliminates DUI all together. I like scubapro's drysuit they're about to come out with, adapted from subgear, the exodry. However, the suit that has really caught my eye is the Waterproof D1 as you can take out the liner so it has a larger range of temperatures at which it is useful, and I hear its tough as nails. Obviously I've read about the downsides, ie the abrasiveness of the liner. This suit is clearly a bit outside my price range at $3100, however I found a lightly used one for $1200 and that's kind of the reason I'm asking the question now to see what people think.
