I don't have experience with that particular suit, but I've been diving a DUI CF 200 since 2008 and was issued a TLS 350 SAR suit last spring. I'm very happy with the performance of the suits and DUI's customer service. Bite the bullet and get zip seals from the word go. I've been using their zip gloves and like them because there is no big lump around your wrists from the dry glove mounting system. You'll also want the Kevlar knee pads because of all the zebra mussels. In the photo I'm wearing my CF200 diving Port Washingtons harbor on a January day. The water temp was just above freezing. Air temp in the 20's. That suit still had the Viking pull over glove system at the time, but it has since gotten zip gloves like my department suit.
