Just bought a set of these for my '07 TL. QUIET is an understatement. Sidewalls do flex a bit but not bad for street driving. Wet traction is excellent both in hard cornering and acceleration. Very happy with them so far. I haven't had to drive on them in snow yet but after the Michelin MXM4's, I'm expecting a huge improvement. The Michelin's were dangerous and scary. I would have tried the Bridgestones Potenza RE970AS based on the reviews but they were back ordered. The comments in the DWS reviews about steering response had me a little concerned but after driving them, and considering the price, I have no regrets.
I didn't buy these from Tire Rack but since I used the site to research them, I figured I'd throw my $.02 in. Thanks Tire Rack, great site.
