I will try this again The last time I tried posting this it didn't work. Last year I made up 50 fishing noodles [10 of each depth starting at 5 ft]. They are 14 inches long with PVC pipe in the middle using the standard 2 or 2 1/2 inch diameter noodles. After using them I think they need more bouyancy. I seem to have trouble with the hook not setting well in the fish. I am wondering if I add expanding spray foam inside the PVC, will that get me the bouyancy I am looking for? I hate spending money to make more that are longer if I don't have to. Thanks
