WHAT IS YOUR PIN KRYPTONITE ?
spools? serrated pins? mushrooms?barrels ?
graduated spools? any combo of the above?
personally my "pin kryptonite" is GRADUATED SPOOL PINS...
usually found in YALE , CHUBB and others , these pins are graduated in size, tall and long,
graduated down to stubby,short spools.
combined with high ,tweaked-out tolerances, give me the most resistance.
