Wow, that story got my heart rate up John!  I agree, I like to have my shut down fully ingrained in my muscles (so I don't have to think about it) and I like it to happen right away.  I do it by turning off the flight critical bus breaker (it's a combination circuit breaker /toggle switch) which kills the power to all flight systems.  I do have an emergency bypass switch in case of breaker failure but it is normally off.
 
Nothing wrong with killing the engine via fuel pump shut-down but keep in mind an emergency procedure in case you need it to happen *right now*. 
 
I seem to be inadvertently sending two copies of my messages to fly-rotary after switching to new server and using G-mail.   Sorry for the inconvenience, I'll get it figured out soon.
