All my vanes are getting trashed uniformly. At this rate, I will be refletching every week.

How do I align center shot? I thought about aligning the center of the biscuit hole with the string and the center of the limbs, then I realized that the string is centered on the top lim and off set on the lower.

Now knock height: What is the proper position? My old setup (tm hunter) was having the knock point 1/8 inch above square on the sting.
