I got these wheels on my legendary demon (sick deck!) when i first got them i did some cruising and hard carving. After about an hour of hard carving i slid them. They didn't chunk but they were really choppy. I kept sliding them by the end of the day they were decent. After about a weeks they got SO smooth, like a mix of butter and silk =). I've had them for almost a month and they haven't worn down that much, and they haven't coned much either. I flipped the wheels (their center-set) and broke in the inner lip and now they slide even better. I highly recommend them to anyone who wants these for sliding, carving, ect. And they're 81a so they grip well.

i've had these wheels for about a month, using them for high speed slides and general downhill. they're extremely grippy to start out with, but once broken in they slide smoothly and predictably. they're centerset, which is nice for those of us who slide a lot because you can flip them around once they cone and cone them back out the other way. these wheels grip well and slide when you want to. for high speed sliding and drifting on your favorite DH runs, i haven't found a better wheel. i give them a 4/5 only because they wear down fairly quickly; i've had them for about a month and they're already worn down to around 63mm. other than the quick, i absolutely love these wheels. i will be buying another set soon.
