Crank and Cam Trigger Set up - Hall Effect Sensors

I purchased two Hall Effect sensors to run a crank and cam trigger set up. I was originally going to go with the Nigel Petrie designed one however looking at them at WTA and trying to get some help from Nigel i am not convinced in the crank triggers design.

It looks likely there is too much opportunity for vibration in the design and looking around i was much more impressed with the Ross Tuffbond set up

I think i might go with the Ross one along with a Ross balancer
