Just an adendum to my last email, thanks for all the replies sofar. Much appreciated, will reply privately. I'm not really sure if I need a dual outlet valve, hence the question. It would not be difficult, or particularly expensive, to try the H valve option. Plus I could route the hoses as for doubles (preventing hoses sticking out all over the place and allowing easy access to valve knobs. The reason I'm replacing the MK10 is that there is a nick in the grove that retains the stem O-ring. I have to service my MK10 every few months as the leak (just a bubble every couple of seconds when first serviced) becomes quite noticable (stream of bubbles) after a little while. Replacing the body of the MK10 would probably cost as much as a new Apeks reg and the Apeks regs are easier to service and maintain (the nick in the O-ring groove on the MK10 is from a poor service, not suprising though given how hard it is to reach that particular O-ring). I became a service technician for Apeks recently and this course confirmed my confidence in the quality of there regs (got to meet one of the engineers who designed and tested much of the gear). The only reason the Scubapro swivel regs work well with single tanks is that you have the extra port on the bottom. Meaning you can have all hoses angles away from the valve knob allowing easy access. This is not possible with the Apeks swivel regs (plus you have the extra O-ring you don't need). The only other option I've considered is the Apeks flat head first, this should position the LP hoses well on a single outlet valve but the HP hose is still sticking out at an odd angle. I have considered doubles but doubles would add some extra drag and make my setup harder to handle above the water (wouldn't fit in tank racks, heavy to load and unload (my back gets enough of a workout as it is :-), etc). I guess small doubles would be an option but not the best for double dives (where I'd normally take a second tank). Plus I'd have to spend the extra dough on a new wing. At present I have a nice, simple, compact setup which works well for the shallow rec and research diving I do.
