why not just lengthen the octo hose length? and why do I want to give away the only reg that I know is working? although I do make it a habit to breathe off my octo at some point during the dive so I know it's working.
I can understand it if you are carrying multiple gases but for rec divers it's just one gas.
Beside what other mention, here is my take on this.
40" hose is pretty long enough, if you let it hang on your side, to drag on bottom, get caught on things, trap things into mouth piece .... In other words, it is more like to to render the 2nd stage non-functional or less than functional during a dive. Any longer hose in this config will only make thing worse. On the other hand, a 2nd stage on 22" hose bungee on your neck is highly unlikely to turn non functional. Keep in mind, you have make sure it is function during pre dive check so you also know it is working and more importantly, it delivery gas that is safe to breath in any depth.
A 40" hose octo dangle on your side, you will need a few second to location it when it is most needed. Any longer, it will only make it worse. Donating what is in your mouth is immediate. That couple of second can turn a OOG diver into panic. Chances are the OOG give will grab what is in your mouth anyway, so no, it is you looking for your 40" octo for air.
If you understand why this is better for multiple gas diving, why not adapt the same concept for all kind of diving? Same procedure, same muscle memory regardless.
Also unless you are in an environment where you just can't ascend immediately why would you want to swim side by side for any distance? I always thought getting to the surface as soon as safely possible was the best course of action.
It is all about options here. Even in OW diver, direct ascent although is possible, but may not always be the best course of action. Such as in high traffic or high current condition, it is a lot better to return to ascent line (if other situations permit) then ascent. Having a 5' or 7' let you have this option comfortably. With a 40" hose, not so convinent.
