Chico - I see now, misunderstood... That would be a good compromise, and snow grip would be almost as good.
My Contis are really very good in the dry, but certainly not as run-on-rails grippy as the stock Potenzas but no complaints. I can feel they're harder compound. Since I actually had the car delivered with them mounted and the summers in the back and trunk, I drove 5 months with them on, then changed to the summers (evidenced by all the green in the background of the winter tire pic) when I returned from Mn in July. They really bite in hard under fluffy and hard packed conditions. I would turn off the DCS to play a lot, and I could toss the car around easily and with full control.
Koes - I have 13,000 miles on my car, most of those are with winters. Maybe 3,000 of them on the summers. No appreciable wear except for one autocross worth, and that was pretty smooth, I'm not a thrasher. The winters still look plenty meaty.
petrashevsky - $1000/set/can - $800/usd for tires alone, that's exactly why I went to 17" for winter. My 17" Pruvens with the Conti's mounted & balanced including tuner lugs were $800 through the dealer. I was informed that I got "The discount", but who knows what that might have been. But why hassle with mounting tires every 6 months when you can change them in the driveway if they're on rims, for the same price? Mark the wheel location when changing them out and you're golden. Mounting & unmounting is not good for the tires & rims at all (sidewall stress, belt slippage and distortion, bead damage, etc,). Some places down here won't do tires that were previously on a rim.
