Invest in some Super Glue (or similar product) and keep it in your boat. I use it all the time for hollow bellied swim baits as well as frogs. After you tear one up a bit, remove it amd replace it with a new one. Now, take the "used" bait and glue the torn areas up with the super glue (where the hook comes out and also where the head by your knot). Toss that one to the side for a while and let it dry, then reuse it. You will be surprised how many times you can reuse one by doing this. Also, I like to put a drop of super glue on the hook shaft where it attaches to the head of the bait, or the screw lock. This really helps hold the bait in place too. When hollow bellies first got popular and Basstrix sort of had the market cornered (which was before many other companies had their own versions), this method saved my rear a few days as I was able to extend the life of the baits which I had very few of anyway. I still do it just to get more bang for my bucks out of each bait.
