Ed,
  I prefer the Fuel Pump shutoff method.
  On my airplane the fuel system will remain pressurized for a long time after shut down.
  I don't like the idea of highly pressurized fuel inside a very hot engine compartment.
  So by turning off the fuel pumps with the engine still running it serves to de-pressurize the fuel system.
  This way if you do happen to get a stuck open injector it will not flood the rotor housing with fuel. 
  It only takes a second or two for the engine to quit after fuel pump shutoff.
  Jim
