Poor me, All my cave regs are DR 1208/2015. Kinda like Russell said, some can't tell the difference. It had been a long time since I dove anything but the DR's. Met some friends in SoFL today and went out from WPB. and dove my salt water gear which includes my Atomics :smt086 Pretty noticeable difference.
However, thus far my DR's have proven themselves to be reliable, simple to service and easy to get parts for. Since I am not presently affiliated with any dealers, it is unlikely that I am going to change the stable of cave regs any time soon. :smt102
