Shortstringing , works well on a 2 cam bow , for maybe 1/4 to 1/2 an inch , other than that and your messing with specs that realy do have something to do with the preformance of the bow . It may allso be dangerous to prestress the limbs . Shoot them the way they were designed to be shot . Limb failer can be very harmfull , either to the shooter or bystanders .
