I am ten pounds off you so we are pretty close in weight so wheels should work roughly the same. :/ Those are like 96a if I remember right. When I skated them they gripped good on a fresh floor but did not have a chance to skate them on "bad" floors. I could see how they could slip a bit on "bad" floors. I have been skating Backspin Deluxe blues for about 3 or 4 months now and I like them a whole lot. They are supposed to be 96a but I don't think they are. Feel softer to me, could be wrong though. Any
