Hey Macdaddy, My " shop" is about 20 miles. I have been shooting bows and working on them for about 20 years, and the guy that runs the " shop" I buy from is a great guy, and treats me right, but he is not what you would call a " pro" at setting up bows. Nub, the tech at Mathews said the bow should be 35 3/4" ata and 6 5/8" brace height with the holes in the cam parallel to the string (not approximate). This is all I have to go on. The setup according to Mathews is pretty straight foward and doesn' t allow for any tweaking or playing around. My main problem seems to be the Zebra string and cable stretching. I am going to set them back to factory specs when I change my cam (ordered the bow 27" and put a28" cam on and now find 27.5 is what I need[:' (]). If the zebras stretch again, they are history and Winners choice will be on the way Don
