I was thinking the same thing...on both counts.
I have Geolanders all-seasons' on both my summer and winter rims and have no complaints about the ride they provide. I wouldn't mind a little more grip in the snow though, and M/T's would probably be the answer, but so far the A/S's haven't left me stranded so I'll most likely just stick with what I have until it's time for replacements (or someone wants to swap).
