Most guys that are running these new MOSFET boards that have on-board microswitches are going to the the SPEED externally adjustable triggers. Even thought it says HPA, the HPA systems actually uses a tiny board with a microswitch.
You get a stop setscrew so the trigger will never over travel to bust the switch unlike the older MOSFET systems that uses a original trigger trolly. It also has a pre travel set screw. The biggest bonus is a custom light pulling spring.
