The Ds-4 rocks. The 1/2" thing is still a gimmick, and the DS-4 doesn't have it or the swivel, or some hokey angled ports, so it works out to be a good reg. It is equivalent to the US4, but probably a better choice for cold water because it is sealed. You keep referring to "breathing like a dream". IMHO regulator performance is a non-issue with just about any reg these days. Below 100fsw, reg performance doesn't come into play, really, and below 100fsw, you are diving w/ helium and reg performance jumps off the scale. I find properly tuned regs all breath the same, very well.
