1+ on the metal, especially the 2nd stage orifice; I wish more current regs would go back to them (metal vs plastic, don't get me started ).
Best wishes.
Looks like it takes the same seat as a Scubapro balanced barrel poppet. What do you want to bet the orifice is also the same. Unfortunately, that probably just gives you a choice of who you will pay $20+ for a metal orifice.
