ive run them for almost a year now and still think they are great. the wear on them is from the first track session i had when i was scrubbing every turn.... but other then that they are great. my dad tried the RE050 PP and thought they were ok, but hes running the drizza's now and thought they were much better then the RE050's. ill prolly get a set of the drizza's when its time to see how they compare.
