I have had pretty good results with EZ-outs and drills.  One thing I do
it drive the EZ-out into the hole I have drilled before I try to back it
out...that seems to get the reverse threads really locked into the broken
bolt.   I use a big hammer and a drift to rap on the ezout before I put the
wrench to it..when surrounding elements permit.
