I just got two of the new Bladebuilders board as seen in this thread: http://forums.thecustomsabershop.com...ear-Down-Guide

I was planning on upgrading the clash and swing sensors, but am confused by what looks like to be two swing sensors and a clash sensor on the board. Does anyone know which parts correspond to these marks on the board?

F1
C1
SW3
SW2

Thanks!
