RE: Hoyt Vector cam timing?
One more note.
Most shops, even the good ones are not going to be nearly as anal retentive as we as the bow owners can be. Setting the timing perfectly takes time as well as many trips in and out of the bow press.
If you are really looking for a perfect tune, then the pro shop is not where you will find it. They will most likely get it close or good nuff' for hunting but it will be far from optimum. There are exceptions, but they tend to be far and few between.
If you truly have the "disease" then one of the best things you can do for yourself is get your own press and do your own work. Something like a Bowmaster press is generally pretty inexpensive, small and easy to work with. Couple that with the knowledge that you can get from forums like this and you can easily learn just about everything you need to know about setting up your own rig.
