On my hammerdin I use 10pts Resist Fire to have 85res while wearing waterwalk, so I never need to switch boots. A further 1pt res lightning and 1pt res cold, and switch when you're about to get hit (after dueling some foh's you'll get the timing right) the 13X extra light res I get from that almost completly negates conviction on it's own. Coupled with the 100+ stacked res I already have, I'm pretty much always at 76 res when they hit me.
