How important is the adjustability of the breathing resistance of the second stage? I have been looking at getting a reg set and I am still trying to decide what to get. With the rebates going on I have been thinking of getting a Legend LX but for cold water recreational diving do I need all the bells and whistles? Or would saving some money and getting the Abyss be reasonable? I guess my real question is how to decide how much regulator you need? Right now I dive in the PNW so I know I need something for cold water but after that how much will a inexperienced diver benifit from something like a Legend or a TX50 over the Abyss? In a year I will get commisioned as an Officer in the Army so if I decide to expand my diving requirements I will easily be able to afford upgrading my gear. Right now I just need something for single tank diving that can be serviced anywhere in the world and handle any rec diving situation that I could incounter where ever I get stationed (looking in Korea or Germany's direction(assuming I don't just get deployed to Iraq or Afganistan)) .
