GREAT wheels. I've had these since June 2011 and its now October 2011. No flat spots, and I powerslide a LOT. They are pretty slick, and now that they're worn down a bit, sometimes I get into a powerslide unintentionally when I'm turning hard but that may be just because I ride really tight trucks.
cost effective, just make sure you get a bigger size if you powerslide so you won't need new wheels for awhile.
