I actually disagree. Their regs are stable, but aren't real robust... the seats are kind of weak and any debris seems to mess them up. I like the violent series (PE) SL3, hyper 2-3, BL 360 and AKA in that order. The dye hyper series and the PE SL3 are bulletproof as is the 360, but I hate the input hose position on the 360. The AKA regs are still solid, the SST is my favorite, but the output pressure is a little high for this application. I have never been a fan of CP regs. At all. They're phallic and don't perform particularly well.
All that to say a hyper 3 (standard threaded) with an angled collar would be my top pick for the DM.
