How do you like those winterforce tires, I have been thinking about putting them on my pickup.
For an economical winter tire, they're great. And of course, any winter tire is better than an all season. I like to say, All Season Tires Suck In All Seasons.

I do think that the Hankook iPike is better on ice though. But, I'm not sure if they make the iPike W409 in a Sky/Solstice size.
On the Trailblazer, I have the truck version, the Winterforce UV. I only have about 500 miles on 'em... so I can't give an accurate review. But, again, they are leaps and bounds above the Wrangler ATDs all season that was on it previously.
