If a limb is cracked, would I still be able to shoot it? I continue to shoot the bow - no problems, no excessive noise, everything is right on line. If the limb(s) are cracked, is this under warranty? I thought it was only the riser on Mathews that was lifetime warranty. The pro shop that put this together did not include any manuals, warranty info., hat, pin, -nothing. I still have the reciept though. Can I register the bow online?
