The Blizzard is a very good choice for where you live. I have one that I purchased back in 1995 that I still use today. It is one of the older models with a heat sink on the exhaust port. I frequently dive in 40 F 60 F and never had a problem with it freezing up on me. Even when I breathe through it on the surface after a dive in cold temps, it keeps on going never freezing.
Over the past twenty some odd years I have purchased quite a few regulators. I own two Scubapro G250s MK10 & 20, a set of Dacor Pacers (which I recently sold), a Sherwood Blizzard and a Sherwood Maximus setup, and an older Poseidon Odin / Jetstream. I have never had a problem with any of these regulators at anytime. Some breathed slightly better than others but not by much. I enjoy some of the comments on this site from divers that have only used one or two regulators their entire life. I always appreciated the moisture retention of the Sherwoods over many other brands. The Maximus, Blizzard, and Oasis have this feature.
Now if you plan on going into some kind of Extreme Tech or Deep Saturation diving way over 130ft I would use a couple Kirby Morgan Super Flow regulators that have been tested to 1600 ft and screw everything else. Im not that crazy so Ill sick to what I have. LOL
