Twisting the Cable will have little to no affect on your cam, timing, peep turn, and impact. All of these are affected by the string, if you twist the string, this makes it shorter, therefor rolling the cam over more forward in the undrawn position. Just make sure they check for cam lean and twist the yoke to get that right. If you want to check for cam lean and they don't know how to do it. Place an arrow against the top wheel or cam and just rotate the arrow down towards the string, it should align perfectly with the string. If the arrow angles over the string or away from the string you've got cam lean.
