The invention also includes a method of testing differently configured gage pads employing a single earth boring drill bit, a method of replacing the gage pads of an earth boring drill bit at the drilling site, a method of customizing an earth boring drill bit to include one or more gage pads of desired configuration, and a method of altering the balance or net imbalance of an earth boring drill bit by replacing at least one gage pad thereof.
