Im installing a used set of richmond 4:10s,im currently at a 0.40 shim with good backlash,The compound shows that the coast side is high and towards the toe(inner end of ring) the drive side is a little low,but not bad and towards the heel(outer).since the drive is not bad should I go with what I got?is that normal that the coast and the drive are in opposite ends of the spectrum.from a standpoint of high and low, and heel to toe?
