Yeah... Put the suit back on your list. The inherent stretch in the fabric is a much better, cleaner solution to movement than an extending torso. It extends more and makes for a much more comfortable dive with less gas necessary in the suit. Less buoyancy, too, than most trilam fabrics. Combined with less gas needed in the suit to maintain flexibility, and this suit really weights out more like a 5 mil than a drysuit.
It's awesome.
I've heard lots of people claim that the plastic TiZip and YKK zippers aren't as durable as metal ones... But I've had something like 30 different drysuits over the years, and the only problems I've had with zippers have been with metal ones. The teeth can bend and break, and the area around the zipper eventually frays and gets caught in the zip. There's also a constant need for waxing. Plastic zips have none of these problems, and virtually disappear underwater. They're great.
I know that not long ago DUI did a test on plastic vs. metal, and they hooked the two up to a machine and zipped back and forth quickly for many thousands of cycles. The plastic failed... Which to them proved the superiority of metal zips. I believe, however, that the plastic zip failed due to the heat of zipping back and forth hundreds of thousands of times very quickly, and in no way reflects a real-world test.
Meanwhile, in the real world, the plastic zips have proven to me to be a lot less problematic than metal ones... And more flexible, flatter, and less needy. I wouldn't buy a suit with a metal zip today.
I've heard, too, that a plastic zips can pull apart and separate laterally, but in 1000 dives with plastic zips, I've never seen it happen... Yet I have seen it happen with metal zips. I suspect that's because plastic zips zip together flat, and metal ones "mate" high and spine-like. When the two are pulled laterally, the plastic zip is pulled from a point of strength. The metal ones are rotated apart when pulled - a point of weakness. One bent tooth or fray and guess what? It'll come right apart. Plastic doesn't have this issue.
I visited Halcyon a month or two ago - who is the exclusive US importer of SANTI suits - and rhe drysuit guys there expressed a deep distain for plastic zips. They told me that they had many times more issues with plastic than metal... But my experience has been opposite. I fail to understand what they saw was the issue with plastic zips, despite me asking dozens of questions in an effort to understand their opinion. I simply disagree - plastic zips are the best thing to happen to drysuits since hypercompressed (or "crushed") neoprene... Which is far superior to trilaminate material (which is superior to standard wetsuit-type "compressed" neoprene).
Unfortunately, because drysuits last decades - and because worldwide drysuit sales are very small (something like 1500/yr - yes, I was shocked too), tech advancements in the market take FOREVER to come to fruition.
Trust me when I tell you that hypercompressed neoprene, nonextending torsos, plastic zips, and flat, nonadjustable exhaust valves are the way of future drysuits.
