I just purchased and installed new 60X cables and string on my 2008 Tomkat. When I set the cables to get the proper axle-to-axle, I can only get 50 lbs of draw weight on a 60 lb peak weight bow. Limbs are cranked down all the way. If I twist the cables, I can get 60 lbs draw, but then the axle-to-axle is about 3/16 too short. Do I need to twist the string more when I've got the cables set for the proper axle-to-axle? How critical is the axle-to-axle length? Or what? I'm stumped. John
