I've agreed to help my neighbor tune his cam & 1/2. Never owned one so I did some reading that has me a bit puzzled. First, when they say to advance the top cam a little do they mean it should hit the cable, on draw, before the bottom cam or visa versa? Secondly, when they say to twist the yoke to adjust the cam lean are they refering to brace height, full draw, or something dynamic? I realy enjoy helping people out but I don't want to drive myself crazy in the process so any help will be appreciated.
