    So you don't see any difference between MK11 and MK25 except the hose routing ? They breathe the same ?

    pretty much. I don't dive cold enough water to worry about freezing.

    I agree. The co-founders of Atomic, Dean Garraffa, and Doug Toth, both came from sp and added to that company's success. When Dick Bonin, co-founder of sp was forced out by the suits, the company is not the same as it was in the 70's when it seemed like every other day they were inventing something new. That's what happens when you take divers off the payroll. It's also interesting to point out that sp was founded in 1963.

    At present I own 3 sp regs
    1- mk5 first stage, pilot second
    1--mk5 first stage, balanced adjustable second
    and 1- mk25 first stage, a700 second. My wife has the mk25 first, and a g250 second.

    Initially, my a700 howled at the surface or shallow depths. It has already been refitted with a new diaphragm, and that problem has been solved.

    On a recent trip to Cozumel, in 5 days of diving I did 16 dives, evenly split between the a700 and the Pilot. At or towards the end of every dive on the a700, I got dry mouth. Something I have NEVER DONE with a sp reg. This did not happen with the pilot. Nor has it ever happened with the balanced adjustable.

    I know people are going to laugh when I say this, but imho, if I were stranded on a desert island, and I could only bring one reg, I would bring the mk5, balanced adjustable. To me they are just bullet proof. At one time I owned 3.

    But right now, I would give Atomic a strong look.

    I got the Atomic ST1 and find it does not breathe that smoothly. Had it checked by the LDS and no change. I may call Atomic about it, but the breathing resistance goes down in two steps as I inhale, and the cracking pressure seems high.
