1) Too many variables. You’re last paragraph illustrates this. 2) I’ve been using Kool Stop dura and v-type pads and don’t recall having a chunk of hard debris seat in a groove. The shape of the grooves and the angled “plow” tip would seem to lessen the chance. I can understand the concern on crushed rock paths, which I don’t have here, though. Perhaps switch to solid blocks to eliminate the issue.
