RE: Hoyt Vector cam timing?
One quick note about the timing. I have always found my C.5 bows to shoot best when the top cam is slightly......very slightly overrotated. The cable should be settling fully into the channel on the top cam when the bottom peg is no more than 1/16" from contacting the cable.
If they are dead even it will not make too much of a difference, however if you are looking for that extra little bit of shootability then slight overrotation up top will work.
After getting the cams in time, you should use a version of the creep tuning procedure to get things perfect.
