Subject: DIN/yoke- shear force and O rings

     There is no doubt in my mind that the DIN design is more secure than 
     the yoke design.  Still, I'd like to hear some first hand "horror 
     stories" about traumatically dislodged yokes. Most of the arguments 
     against yokes make sense, but are not backed up by real incidents; 
     only theory and conjecture.
      
     -Has anyone had a yoke o ring failure as a result of a bumped 
     regulator?
     -If so, did it occur in the water, or when dropped off the roof of a 
     camper van?
     -Would a valve protector (Cage or rollbar) have prevented the 
     incident?
     -And what about (gasp) those crossover "cheater bars" that they used 
     to sell?  They look suicidal. Anyone have a bad experience with one of 
     them?
     
     Naturally I'm referring only to tanks rated at 3000PSI and less...
