Buy a selection of at least four replacement tips (the salesman can provide sizing help) and some wader-repair rubber sticks. Get a box of matches and a sheet of 300-grit sandpaper. Throw it all in a zip-seal bag, and leave it in your tackle box.When misfortune strikes, grab your kit. Clean the broken tip with sandpaper, and find a new one closest in size. Heat up your rubber stick and goo the end of the rod. Slide on the tip, quickly line it up, remove the excess, and let it sit for 10 minutes. You now have a permanent repair.
