back when we had the parking block slappy jam at the bridge, i took a set of indys down to the axle in about two months. i really liked that thing.
but most of my life, it's taken about a year or so to get there. except for stage 10's, which must be a softer alloy, since now i can't seem to get more than 5 or 6 months out of a set of trucks.
i remember reading about tom knox grinding a set of indys to the axle in ONE DAY. i really wish that would've happened now, during the "everything a pro does is filmed" days. that must have been the most epic slappy session ever.
