Dave, please see www.capt-jt.com and read his story about a recent Doria
death he had the displeasure of doing the body recovery on. A mitigating
factor appears to be that the victim lost the down-line and, due to a
configuration similar to the one you favor, got so winded getting back to
the line he apparently had a CO2 blackout, sank like a rock and died. He too
had more dives than God but is still dead, dead, dead.

IP's learn from mistakes, usually gleaned from the pile of rubble and large
hole in the ground the pilot-in-error made. I am sure you have many stories
about this guy and that guy who augured in due to this mistake or that
mistake.
