O.K., your friend has a cracked limb on his 10pt and the factory replaces the defective limbs in a weeks time.  You now have a set of busted limbs and customer service admits they having problems with the TL-4 limbs.  Sounds like they're being honest and honoring the warranty on the limbs.  I wouldn't be so quick to dump 10pt.  Horton, too, has great customer service, but their xbows have been known, on occasion, to have a cracked limb or two. :roll:
