I have to admit, price aside, I'm truly intrigued.
The D420 had me head over heels. The center balanced design is truly better than barrel regs, G260 included.
But implementation is challenging, especially with ANSTI being the governing metric.
While I love my D420, the plastic knife edge execution is suboptimal. The 1.3" cracking effort is frustrating until you get in the water. I understand why, but I still don't like that I can't roll on my back and photograph like I could with the D400.
And the implementation of service instruction is abominable for techs that aren't old enough to know the D-series.
So maybe Atomic will do better. Coaxial is quite the tease. But Atomic's history with their service manuals doesn't inspire confidence that they can teach techs who have never seen a center-balanced valve to repair it properly.
Yeah, I'll buy one for the team. We'll see what it turns out like.
