I'm interested in the Dive Rite Regulators, but the local dive shop that I deal with usually substitutes the Dive Rite 1st stage with the Scuba Pro MK2 Plus, as a way to get around the DIN/Yoke problem. I dive mostly in the Great Lakes (cold fresh water), and have some doubts about using the MK2 Plus for cold water diving. The guy at the shop says that they even use this reg set-up for ice diving. I'm just not sure though. What do you guys think...is this a good set-up, or would it be better to use the Dive Rite 1st stage with the DIN/Yoke adapter?
