I keep a set of lefthand drill bits just for these scenarios. Drilling the broken remaining bolt progressively larger with a LH bit does a good job, and when the hole is large enough the bit usually catches it and turns it right out without an easyout.
I hear everyone say how well the LH drill bits work for them

I have had a set I got from snap-on for years and years
I think they have worked twice,
I almost always have to use the ez-outs still
(but maybe they are loosing it up for the ez-outs)
