Someone in this thread has had a pony yoke O ring extrude at depth....
I swapped the valve to a pro valve on my pony tank and converted one of my reg sets to DIN. Cost me a $100 total, but the valve on the pony needed replacing any way as I broke it. Eventually I'd like to get everything converted over to DIN, but like you, the expense isn't justified right now. Plus, I have the pony now, so that alone eliminates catastrophic back gas loss being a major issue.
I have my pony on. I think a pony and stage/deco tank can be viewed a little differently. A free flow on a pony shouldn't be a cause of too much concern, it's purpose is redundancy for a catastrophic loss of main back gas while recreational diving (you still have other options). The stage/deco tank on the other hand is gas that is part of the dive plan. I would think a severe loss of stage/deco gas could create issues so eliminating the potential for lost gas is more of a concern and thus the valves are closed.
