I, for one, always double check placement to ensure that I can reach all
three valves behind my head.  Mostly, to be able to cut off a regulator 
in case it begins to freeflow, and I cannot stop it.  I keep the 
crossover opened only about single turn, so that it can be shut off 
quickly.  Not that I am under any illusions about how much good it would
do in case of an o-ring extrusion from the valve. 

IMHO.
