What blades were you in before? My DD went from Comets to the Lites (which are basically the same profile ast the Aces) - and her Comets were worn down to the end of their usable life. She had an adjustment to stop her toe-pushing on them, and the different rocker took a while to get used to. Weirdly enough, however, she had good edges from day one ... and her edges were a problem for her previously ... However, the spins did come back ,and they came back much better as the different rocker was easier to spin in (harder to land jumps in, but, that's another story).
