My whisker biscuit has recently experienced a catastrophic failure.........Has anyone experienced this or maybe I should ask "Is this common?".........I've been thinking about a drop away rest for a little while and am thinking this might be the time to make the transition instead of replacing the busted parts of my biscuit......Its either $20 to fix or $110 to replace with new rest......If the biscuits are prone to breaking, I'll make the jump. So speak up.......
