Okay, but you are changing the goalposts a bit, aren't you? Your original statement was that the traditional rec setup leads to octos dangling in the sand, silt, and rocks and getting clogged, or that they might be cracked and not working. I asked how do you know your alternate is working if an OOA diver grabs your primary and you need to use your alternate. Presumably, your answer would be that you checked it before your dive and that you have it secured on a bungee under your chin, out of the sand, silt, muck, etc. Well, my octo isn't exactly under my chin, but it is not far from where you keep yours, and I know that it works because I check it before every dive and I keep it secured where it's supposed to be. All divers, regardless of their gear setup, should always keep their gear in proper working order and should check it before each and every dive.
So, once again, I say that you should definitely dive a long hose and use primary donate if you prefer that. If you want to argue that an OOA diver will most likely grab for a buddy's primary, and that means the hose should be longer, that's fine with me too (although I would definitely like to see some actual hard data on this, rather than the usual anecdotal evidence that gets passed around). But that has nothing to do with knowing that an octo in a tech setup magically has to be working because, you know, it's a tech setup! Versus an octo in a rec setup likely not working, because, well, those rec divers don't know what they are doing and are just begging for problems.
Dive how you like, but please spare those who don't dive the way you do the DIR sanctimony.
