Favorite book for socks on 2 circs?

[crafty_packrat]

I've just been asked to teach a class on knitting socks on 2 circs in January. I'm kind of ecstatic.

How many of you know the technique? Did you find any particular book helpful in learning how to do it?

I've already eliminated Cat Bordhi's Socks Soar on Two Circular Needles -- I have it, and I find the patterns impossible for a beginner to modify for size, for all that they're rather pretty.
