Nemrod:An octapus is not backup for anything, it is not redundant nor is it independent. An octapus has only one purpose, to supply an out of air BUDDY with redundancy, a circumstance not possible if solo being as you would have no buddy and therefore no need for an octapus on short hose, middle hose or seven foot long hose. However, a set of independent doubles, a single with buddy bottle, the interesting side mount rig all have "backup", I suppose an isolation manifolded double set also, but your seven foot long octapus does not provide any back up and therefore is not an optimum rig for solo diving no matter how great it is for buddy diving in caves.
From the original post:
"I realize the DIR philosophy fundamentally opposes solo diving. How relevant is the gear configuration to solo divers? It seems to me the long hose would offer no benefit and fins would be personal choice. Other than a redundant air source is their any consensus on the best solo gear setup?"
Answer:
I understand the ostensible question, he is asking if the long hose octapus is useful in solo diving and if like DIR divers, who use a fairly regimented gear set up, do solo divers also recommend a rigiid defined gear set up--the answers are NO, the long hose octapus is not useful in solo diving and NO, as you can see from this thread, there is no concensus upon a single gear set up or even it's specific uses.

Nemrod, thank you for correctly interpreting the "ostensible" question. I think your post succinctly answers my original (or restated) question. I did not anticipate that my question would be so cryptic or contentious.
