there you go assuming again....
careful, it'll get 'cha one day. Might not make that 27 more you were talking about. If you look into my profile you'll find that I was trained by mostly the same organizations as you.
First off, I was replying to a poster who was talking about a rec rig. A single tank, no overhead, no roll-off.
Second, you do not donate the long hoes because it is on the right post, you donate it to facilitate exiting an overhead where single file swimming is required during an OOA situation. You do, or should connect it to the right post for the reasons you mentioned (I'll give you that much). Two different things. Further more, the diver may be diving singles with one 1st stage or dual 1st's and a Y or H valve. No one mentioned doubles as the whole conversation has been revolving around rec divers using the long hose.
Quit reaching for straws...
