I've got sort of a dumb question, but I haven't seen it asked before... I just picked up a new 2012 Pantera and want to have my wife use my old Cheetah. It's a 70# bow which according to the manual, will go down to 55#. Since you can back off the limb bolts all the way until the string falls off, what would happen if I just backed the bolts off until it was 40#? It is a 2006, so I'm not too worried about voiding the warranty, but I don't want it to blow up in her face either.
