No I have Conti DWS and this is their 3rd Winter, my first winter with them was very good, they were almost as good as my privious Blizaks. last winter we hardly see any Snow so did not notice much. This winter only couple of 1-2 inches of Snow in last 2 weeks and they still holding on Fair while driving on the 1-2 inch of Snow on the ground.
Now my Rear are at 3/32
and front are at 5/32 so I am just pushing the Rears to last this snow..
So either go with All Season or Summer/Winter setup on two setup of wheels
