After cleaning and inspecting my regulator today, I fell bored and made some measurement. Not sure if anyone care.
G250V: 9.4oz. Like the construction, built quality is simplicity. Hate the use of specialized jam nuts. I wonder where I can find a standard replacement. Venturi adjustment isn't as easy to use as HOG's (or Scuabpro's own A700) implementation Overall, it feels the toughest of the bunch.
HOG classis: 10.2oz. It is the heaviest of the bunch because of the metal front cover ring. Very good build quality. Much better than any Oceanic/Hollis 2nd stages I have used. Like the quality/performance vs cost ratio. Venturi and breathing adjustment knob (biggest) are the easiest to use in the bunch. Jam nut and heatsink can be implemented better. Service kit cost has gone up to the same cost level as Scubapro and Atomic. If you service your own reg, the on going cost is the same.
Atomic B2: 5.9oz. Like the compactness and lightness. Ti inlet tube definitely have advantage again corrosion, zero sign of any corrosion. Atomics are the most complicated of the bunch, has most parts for each function. But fit and finish are the best of the bunch IMO. Venturi is auto adjusted, can't say it is a bad thing. Breather adjustment knob is not as easy to operate as HOG or G250v.
Atomic M1: 7.6oz. So I guess this mean brass inlet tube vs Ti inlet tube are different by 1.7oz. The M1 front cover really is better than B2 front cover for minimizing current induced free flow. But M1's extra wide exhaust does NOT work any better B2's exhaust, or I should say B2's is already quite good (wider than G250V, which is wider than HOG). In fact, M1's wide exhaust gets in the way of the adjustment knob. So if anyone is thinking of swapping B2 exhause for M1, don't unless you are going for the look.
Last is size difference from largest to smallest. As we all know, M1 and B2 are exactly the same size, so use B2 for reference. G250V is noticeably bigger than the rest. HOG classis may look the same size as Atomic from picture, but it is actually bigger in person
In term of performance, I have to say they are all very good. They all feels little different, but I won't say one is definitely better or worse then others. In terms of consistency, one of my HOGs seems to require a little adjustment on the orifice along the service interval, otherwise a perfectly adjust HOG will "leak" a little after some usage. But I think this has to do with the seat material, not the design. Scubapro and Atomic seat material seems better quality than the one came with my HOGs. But the new seat in HOG kit seems different than the original as well. So I will have to use it more to see if the new seat is better.
