Yes the steel cable is part of the venting system and what you need to use and practice with in order to vent properly.I apologize for the dumb question, but being my first setup, I've never had an opportunity to gut another one and have nothing to compare to... is that the little steel wire that's inside the hose that the little steel rod in the AIR2 goes through? If so, yes.
4' is too short to wrap around your body and too long to route just under your arm up to your mouth. A 5' hose is a great length since it doesn't have to be tucked under anything and stays tight to the body. The other option of routing a shorter 36"-40" hose under the arm up to your mouth is best accomplished with a 90 degree fitting. Other than a captured swivel the ones with a bolt holding them together are shown to fail. The 90 degree fitting has a very low failure rate.as for the longer hose on the primary, I do intend on adding that before diving this setup. Was specifically leaning towards a 4' Miflex hose, why do you suggest 5'? It just seems a bit excessive IMO.
