747,
I'm not a "DIR" diver, but that's the exact rig that I dive (with the exception that I dive the older "Z1").
I've never had any issues with either one of the regulators, at depth or in cold (42F) water.
I've been diving the B2 since 1999 and added the Z1 about 2 years ago.

I bought Apeks because they are basically bulletproof. They've been rock solid for a lot of people over a long period of time. There are other brands of regs that also meet the requirements for DIR, Scubapro for starters. Other than the swivel, I don't know any reason why your Atomic wouldn't be fine for DIR but, as always, ask an instructor if you are taking a class and are concerned about gear choices.747pilot:
But I was looking into the Atomic B2, Atomic M1, and AquaLung Legend LX recently.
Ultimately went with the Legend LX, for several reasons:
- Overbalanced makes it breathe a bit easier at depth (though the Atomics are great too)
- Diagphram vs piston; a bit "smoother" WOB which is perceptible vs piston which you can sort of feel "rattling" at the end of the curve
- Diagphram vs piston; can be more easily adjusted/tuned vs needing to be overhauled (even on a boat if required)
- Legend LX is "actually" environmentally sealed, vs Atomics which relies on gunk packed into it to seal it (I forget the details here, but it made sense at the time it was explained to me.)
- Two less swivels on Legend LX vs Atomic B2 (One less than M1) means fewer moving parts, means simpler, means closer to DIR I guess (Protection against Murphy's law if nothing else.)
- About $100 less for the Aqua Lung vs either of the Atomics
Ultimately came down to Atomic M1 vs Aqua Lung Legend LX for me (cold NJ water) and then the sealing/service/adjustment plus price differential swayed me towards the Aqua Lung.
Your mileage may vary!
