That is the question? I was pondering this when trying someones twin 12 the other week and they had a long hose, now as a PADI trained converted to BSAC 15 and a 3ltr bail out man I have a standard octo in the "triangle". So whats the pros and cons for a RECREATIONAL DEPTH DIVER only who dose not do cave diving? I`m taught on an oog situation let them take the reg and grab the bc and control the ascent not send the packing to a meter or so away! Whats the benefits either way please and if there are many benefits should all rigs be with a long hose (subject to training ect)?
