@Mannith Abec rating is not in anyway important in skate bearings. It's a myth. Abec 5 or greater is fine but there is really not much a noticeable differece. The biggest factor is that the raceways and balls are made of chromium steel.
what's your setup like on your evo? ceramics may break under freeride pressure. try to use a bearing with an abec rating of 5 or greater with speed rings and spacers to extend the life. zealous work fine
