I agree, in the sim if you do get runaway stab trim it "really runs away" if you don't stop it in time and by then even two portions of the Capt's meal won't be enough to control it or fly the a/c
Switching off hydraulic supply to the stab trim at the first indication of runaway trim would a very good idea. I do recall though in one of the books by Mike Ray on the B767/B757 where he's totally against the idea of resetting the cutout switches one by one. Wonder why though
