How do you figure on string and cable length with a Hoyt Ultra Tec 2005 riser a set of 2006 limbs and 4.5 spiral X cams. I tried what Hoyt has on their site and the 58.5" string makes the bow a 56lb and the limb bolts are backed off 4 complete turns. I also tried the 2005 setup with the 57.75" strings and that came out to over 60lbs. This bow is a frankenbow but need to get the draw length to 28". It was at 26". 50-60lb bow
