I think the better point is that the regulator is capable of achieving very low WOB numbers.
They ALL are. They are all capable of actually freeflowing, which is to say that they are all capable of FORCING gas down your throat... In other words, NEGATIVE WOB numbers.
From there, it's a matter of tuning the regulator - easily done with a screwdriver and some patience - to deliver to the diver only the gas that he wants, when he wants it.
...Now, where that point is set, exactly, when it comes from the manufacturer, is what these so-called WOB tests are measuring. My point is, it makes no difference, and they're usually set too low anyway and need to be detuned to be functional.
The diver can choose to detune the regulator somewhat. I certainly don't want the thing free-flowing in a current.
...Or when you jump in the water... Or when you accidentally spit it out... Or when you donate it to your buddy because he's out of air...
People seem to REALLY be stuck on this idea of "performance," and that somehow, one reg has better "performance" than another. It's 2010, my friend... Pretty much, they all "perform" the same. Any differences are really just the differences in settings. What's more, if you take the cover off of most regs, you'll see that most of them are made by the same manufacturers and share the same parts... So it shouldn't be a surprise that they all breathe the same.
The mentality that one should be so concerned with "performance" comes from an irrational fear of drowning... That somehow, one of your choices could leave you with not enough gas to breathe. I can tell you that reality simply doesn't support that. The reality is that most of the regs are all identical.
We can assume that the reviewers didn't measure the WOB on the regulators they actually tested. More than likely, they just published the factory numbers and these numbers are the best the regulator will ever measure.
Oh, that's even better. If you walked into a car dealership, and the salesman told you, "This car can go 155 mles per hour," would you choose to buy or not to buy based on that information? I mean, as if the top speed was the most important thing... But even if it was, would you trust the entity trying to sell it to you? If the WOB (as if that's somehow a key) wasn't tested by the testor, and is simply pubished information from the manufacturer, then the information is completely moot anyway. And I don't mean that the information is laboratory-perfect and may not be the same in the real world... I mean, it may be complete bull and have no basis in reality whatsoever, under any circumstances, just to sell someone who thinks "WOB" is a selling point of regulators.
I'm a little skeptical of this approach as well. It is just human nature to recommend the thing you just bought and disparage the thing it replaced. A prospective purchaser can post to a forum like this and get a broad spectrum of recommendations but the problem is that it isn't as broad as first thought. Kind of like the BP/W crowd. Small in number but vocal! Disclaimer: I'm one of them...
Me too. And being one of them, I can tell you that I simply don't care if someone creates a new, "better," lighter, more streamined, "latest and greatest" AquaPro ProHawk BC. When it comes to BCs, "lightweight," "titanium," and "oxygen clean" doesn't matter, either. These would all be pointless marketing schemes that have little factual (if at all) benefit to a diver underwater. Sound familiar?
In the end, a customer can read, discuss and consider all kinds of opinions but they have to make their own decision. As long as they buy an appropriate regulator for the environment and it is from one of the top suppliers, things will work out fine. It might not be the 'best' regulator in any particular regard but it will most likely perform beyond their ability to discern.

You're missing the point.
Look, man... Go to an LDS or a vacation spot or whatever and rent as many regs as you can. Take with you someone who can tune a regulator, then go try them all out. You'll find that the tuner has a lot more to do with your "WOB" than the name brand on the front of the reg...
Not surprisingly, you'll find that all of the regs will pretty much breathe the same...
