I was wondering when I checked my tiller its a 1/8 shorter at the top than the bottom,should this even?the bowtech manual says the tiller should be even.I do know on most single cams they say to just bottom both limbs out and turn them back equal turns,but I did this and its shorter on the top.also could someone tell me what they have there center shot set at?I think its supposed to be 13/16 from the inside of the riser.
