have you had any experience with them verses something else?
My other regs are Aqualung Titan , Sherwood Bruts and a Sherwood Blizzard. The Blizzard is my go to reg for single tank dives, the DG03 are for doubles and stage bottles, the Titan lives on an O2 bottle since, despite detuning, it tends to freeflow (has enviro seal) in cold water. They all work nicely although the Sherwoods cannot be used on stage bottles since they fizzle continuously.
