 Come off it , Rod - you are trying to tell us that a manifold is more 
dangerous? You are looking at one failure mode, and ignoring all of the other 
combinations in diving that are equally important, and since we have had no 
manifold failures, more important. If you lose the knob, and the reg, you have 
to isolate, but you are saying this is more dangerous than just losing all of 
the gas out of one tank and swithing to the other ?

 First, you switch regs in either case (to be sure the other one is working so 
you do not come up empty, if not you partially shut don and go to a slow flow
to 
the reg and get moving), then you go to shut off the bad reg. Either that works 
or there is no knob, so you isolate. Now you have lost some of both tanks, but 
at that point you are still better off, and to not have the flexibility of the 
manifold in order to accomodate a situation where TWO failures must occur 
together is a little extreme, espcially since if you TRY to drain you tanks 
through your regs it takes a while?

  Simplicity is having one pressure guage, one back up reg around your neck,
one 
long hose which you breath, and one inflator hose.
 
  If you are breathing the stage and have to share gas, unclipping and passing 
the long hose while jumping to your own backup ( to avoid any possibility of 
having a second person out of gas - yourself) until the situation is stabilized 
is reflexive for a properly rigged diver, or a clusterfuck for a stroke with 
stuffed or no long hose, and a convoluted , multihose arrangement.

    Naked with the magic stone is best, and the closer you come to that, the 
easier it is. - G
