im so happeh ! this thing is a beast >>; three top pins are serrated and there counter part bottoms have one at the top of the driver pin, but i finally got it to pop! now to practice it more n get the feel for serrated pins. i've found that counting the "pops" as the pin passes the shearline helps a bit in figureing out where the top in sits.
does anyone know the average number of serrations a top pin has? the ones in this lock seem to have 3-4
