SS backplate & OxyCheq 45lb singles wing with Genesis GS2000 reg for single tank.
The SS plate keeps weight off of the weightbelt. The wing is nice, though I really have no use for that much lift. Diving big steel tanks with lots of neoprene, thereby requiring lots of lead, it would be the ticket, though.
The GS2000 has been a decent regulator. It doesn't seem to breathe well upside down, and the first stage comes up a little short with two divers breathing off of the primary & the octopus at depth. I have been told that it can be tuned up to be a really nice breathing reg, though.
Aluminum backplate with DiveRite Classic wing & 2 DiveRite regulators for doubles.
Considering the HP steel doubles that I have, the aluminum plate is preferable to SS. The Classic wing seems to work just fine, but then again, I never have used anything else to compare it to.
The DiveRite regulators have been really nice. I wouldn't hesitate to buy another one. Some don't like the swivel that the first stage has, but I haven't experienced issues with it yet.The price is a really big attraction with these regulators. Also, if you want to service them yourself, parts are easily available. But then again, if you don't want to, DiveRite doesn't seem to be as popular in diveshops that specialize in recreational diving. Most technical oriented shops in my area seem to carry the line, though.
