well they make tubes for bass and for panfish, the panish are what i use and are usually 1" to 1 1/2" to 2" tubes. some make them hollow and some make em solid. i use the hollow ones. Some people make their own which is a long process. but for the money i can get a good deal on some southern pro scale head lil hustlers pretty cheap. PANFISH KITS 2 come with jig heads and all.
