Well drove on them for ~800 miles. The ride is definitely softer due to deeper, softer treads. Handling suffers just a tad as it loses some responsiveness. Still very capable.
In the snow, handling and accelerations during turns are excellent. The cabin I rented in VT was up a very steep hill and was unplowed with about 4-5" of fresh snow over a hard packed snow base. No drama, just digged in and went up without a slip. My friend's WRX was all over the place and another friend's TL was stuck at the bottom of the hill. I would definitely recommend these tires to anyone living in the snow belt. A completely different beast on snow with these shoes.
