RE: importance of properly set 3rd axis
I set mine on the medicine stone which sets with the sight mounted to the bow and in relation to the string at static. I then have my string checked using a full draw tool and spot hogg laser so that everything is set with the path of the string rather than the shaft. Since I am shooting a shoot through system, path of the string is true and straight as I have seen using the laser and full draw tool...........so I personally believe this is a better way than checking the sight bar as compared to the arrow at a static point. Seems to work for me......
