Hey, we're back! I had to print it all out just to keep my place.
For both Superman and Swisstrav-The 2 ways to use a balanced first stage with a rebreather (there may be more) that I know of, are a balanced piston, which gives no adjustment control over the pressure, requiring you to use different orifices depending on your requirements. The second is a balanced diaphram. You control the pressure setting and usually use one orifice. BOTH types MUST be sealed against outside pressure. They become 1 atmosphere regulators, always supplying the same pressure to the orifice. As far as changing out orifices goes, the Dolphin comes with 3 and Dreager sells others, your already doing it.
Metabolism- using the Dolphin as an example- just because the jet has 50% on it does not mean you can only use 50% nitrox. Using oxygen gauges to read your use rate of oxygen on a given jet of a given % oxygen, you can then change gas mixes based on your #' s for deeper depths. Take a mix, hook up to a jet, relax at the surface, and read your O2 gauge. That reading plugs into the nitrox depth formula because it gives you your starting O2 level. No, it is not safe, it's a rebreather.
I am presently running something that started as a Ray, is sandwiched between a backplate and a tank plate, with a KISS style O2 system. Things are hanging from it everywhere. I never met something I didn't at least want to try.
I think the lowest mix I used on the semi system was 35% on the 60% jet. Specialty dive. COULD NOT BE USED AT SURFACE.
I sort of, like, hold the O2 gauge in my hand during a dive. That's why it's there.
I have been to Cozumel, Cabo San Lucus, Bahamas, Coco Island, Similan Isl.(Thailand), Bimini, PNG, Honduras, Socorro Isl., and all over the Seattle to Canada area.
Did I get them all?, I tried.
