Consider making the backup (necklace) reg a non air balanced so as to diminish the probability of freeflows, etc. Were I to buy new backgas regs now the choice would be: DS4 + TX40/50 primary DS4 + ScubaPro R380 secondary. > > deco gas would be either Apeks TX50 nitrox with DS4 1st stage or the > > Mk20/G250 Scubapro nitrox. > > >Response: Sounds good to me... it's really hard to beat the Mk20 G250.
