Sorry to resurrect a fairly old post, but I just got a set of these and wanted to chime in.
Got the gForce Sports put on yesterday ($80 from Tirerack) and so far I am very impressed. Back to the OEM feel of the KDW, but with less noise and should have slower wear. I am coming off of a set of Kumho 712's, which are total crap, so anything would seem better probably.

Overall, a very good compromise of price/performance.
