Sorry I haven't been on in a few days.
I attended a seminar at our LDS in which DUI made the contaminated dive presentation. Being a hardcore fan of Viking, I was very skeptical. After the presentation and hands on decon, I started to have a different mind set.
Now I'm no scientist, but what I saw was a contaminated 350 get clean using procedures we already have in place. I also know we wear the seats of our rubber suit out very fast (sliding down canal liners, etc). DUI claimed greater abrasion resistance. Since we have started replacing suits, they have been used in the same manner and are holding up remarkably well.
The suits we are purchasing are custom fit and very well built. The Vikings we were using were stock size and often ran large in some area, causing mobility issues. So far all of our DUI suits (both 1050R and TLS350) have kept the diver dry and we have not run into any problems with workmanship.
Again, I was of the same mindset that you can not decon anything as thoroughly as rubber. Call DUI and find a seminar near you or host one and see first hand, because I can not put what I saw into words.
