912 held their on own on the white stuff too.

You are asking too much for a single tire, good grip is inversely proportional to durability.
Its like Time/Cost/Quailty pick 2 out of the 3.

912 gets my vote.

Hum ... I drove my old RWD car w/o LSD on 912 during a snow storm.   I had to get to a friend's house deep in residential area with un plowed 3 inch fresh snow.  I was able to get around okay, just have to understand they are all season and you will be fine. But they do have trouble going up moderate inclines ...

Great deal considering the price, I got my set of four 195/60/14 for $240 ...
