Take it for what it is worth, limb twist, cam lean, horizontal nock travel all affect arrow travel. My Alien Z, and Alien X shoot much better and are much easier to tune without it. I put Tilt Tamers on both of the Aliens and paper tuning is as simple as eyeballing the centershot cams through rest. Set the string directly through the sight and walk back tune. My Alien Z had such bad arrow flight that there was no way that I could paper tune it. If the Nitrous X cams came back I would invest in them. That being said, most people can tune a bow and deal with the cable slide induced side torque without any problem. I really like the idea of the CCS, but I wish that it had some adjustability to allow for less pull from the cables. The vanes that I use do not need nearly the clearance that the original CCS provided.
