I don't know if you ever used REAL snow tires before, but a snow tire is not built to handle like a summer tire. The rubber compound is much softer and subject to much more bending and flexing than a summer or 4-season tire.
Blizzacs are a very good snow tire , but like any other snow tire, they will ruin your handling on solid asphalt.
I personally use Michelin Arctic Alpine with extremely good results in snow, but I take it slower on bare asphalt.
