Just finished a 1900 mile round trip towing my 911 to the final track event of the season. On the return trip, coming through WV, I ran into some pretty serious snow, could only see maybe 3 cars ahead of me and at times just two tire tracks in the right lane on the Interstate. Loads of fun pulling a 4300 trailer.
But the new Bosch Icons I put on before the trip were great. The OE blades constantly froze up in the joints last winter, but on this trip the Icons worked as well as any winter blade, without the high speed float that the winter blades are subject to.
Not cheap for wipers but worth it IMO.
