tire recommendation 06 Outback wagon

My wife drives an 06 outback wagon. It has about 15k miles on it. It came new with Bridgestone tires. They are great tires but show a lot of wear right now. I figure I might be able to squeeze another 15k miles out of them before I will have to replace them. The car is not driven hard.

The question is what do you recommend for a good winter tire? I have had Blizzaks on another car and they were great. Because of this I am partial to the Bridgestones.

Any help is appreciated.
