Thinking out loud:
'Conventional' doubles hose routing is long-hose primary on the right post and secondary on the left post
In an accidental overhead roll-off (closing of the valve), the left post is more susceptible to roll offs given that the diver is most often moving forward
This could lead to closing your secondary, which you wouldn't notice immediately (eventually you should notice via your SPG)
Potentially you could donate your primary to an OOG diver/as part of an S-drill, switching to your secondary and *oops* no gas
While it shouldn't be a big deal to reach back and turn the valve back on, it's not an ideal situation
Your thoughts? Does anyone reverse their hose routing for this reason? etc
