Depends on whether or not the limbs were at full draw or not. I guess if you are retarded enough to not be carefull of the broadhead and you cut it, first of all it would probably be the serving, big deal you'll survive until you get to some serving material unless you crank a blade into it. If you get so far as to be at full draw and it snaps then no mater what you're shooting, the hunt is over until the proshop checks it out. I personally would rather replace my limbs no mater what. I don't want to put a load into my pants if I don't have to if a limb breaks. If my string broke at rest I would have no problem replacing the string and getting back to work. I probabaly would run some cloth along the limbs to check for cracks, maybe.
