Master switches are fine and dandy, but, the fuel pump should be wired through an oil pressure switch.

Interesting, although when I was stuck at wot on spray with no place to go the master on my panal is what shut everything down, currently the only thing not through my master is the arm switch for the prog controller, and the under hood fire system is on a pull switch hooked to a hood pin lanyard coming out of my dash with a loop, just pull and pray.


But overall thats not a bad idea, maybe a good thing as a redundent? system, but I think everyone argees you just cant be too safe.
