I got my 30" 70# Old Glory in and the draw length seemed short. So my dealer ordered 30.5" cams and got them in about a week(IMPRESSED with this). Now that I have the new cams on how do I know that they are set up right? These did not come marked from the factory like the ones on the bow. The 30" cams were still ok as far as the marks go, just want to be sure the cams are exactly the same to start out with. The a-a is about 1/16 longer, bh is about the same, the only thing that changed was the tiller. Sight pin at 20 yrds was right on. So should I mark the cams where they are or is there a way I can check the cams to be 100% sure they are the same. sjb3
