Kev, with an argon bottle regulator you use an overpressure relief valve which sings like a bird when it goes off, alerting you to a reg problem so you can shut the valve off. When a second stage reg acts as an opv, it is indistiguishable from a accidental flow unless it is either bad, or happening constantly, but yoi do get the "signal" one way or another. Not a real big deal, but I personally try to dive the same rig no matter what, although I have and still do use the back gas as inflation on a dive , like in Mexico, where minimal gear was easier to lug around. This is all not that big of a deal so long as you have the bc hose on the right post, so long as the left side does not interfere with anything .With the argon bottle, remmber that the hose is UNDER your harness, not over, so is held up and is out of the way of everything. When run from left to rught under the arm and under tha backup light but over the cannister light, it also does not interfere. You be the judge of whether the left side interferes. In general, if you can solve more than one problem with a gear solution, use that solution. The behind the neck is just one more little trick or fine point that may or may not be a big deal, but the mind that makes the detail count is the mind that generally has everything thought out in advance, and is just a good habit to get into. However, this is not a big deal at all, and less gear is best if it works. I only focus on one kind of diving for my real diving, and I ask my guys to do as if they were in Leon Sinks all the time, for obvious reasons. For instnace, I ask them to use the c-4 insulation eveywhere, so that when the shit hits the fan and they have to swim, they are used to swimming and operating in C-4, and do not cause themselves futher problems when it counts. To be truthfull, this kind of discipline is why we can dive once in a while and hit it out of the park every time, and Bill Stone's cast of personal preference strokes took 90 days of diving to follow our line halfway in their best attempt and fell on their faces - the details - which all of them said I was such an "asshole" about. So I agree with you and yet I don't really personally do it that way.
