Using a screw lock hook for me helps with the tearing issue. Also if your not using a screw lock and are using a weighted hook, make sure to start your hole in your bait with the pointed end, remove and than wet your eye of the hook and fish it through backwards through the nose of the bait. Other than that.... Mend it!
Thanks for the tips guys, already rigging the hook through the belly, the FISH are the ones doing the damage. Sounds like Mend-It or some superglue will be best here. Time to tinker with some materials!!
