ya rope/chain to a tree and hang that over a branch lower it to like 5 inches above the water and use a 3+ foot wire leader 400lb test i beleive (sailfish quality) and hook a 2 day old chicken thy to it.
i beleive on swamp people they use 550 para cord which saposidly 550 lb test but i dont know how it stands up to teeth
im in florida on a guys land that said he had a few in his dikes but the biggest one so far was 7 foot.
i know the ones on swamp people look they have more meat in the body part but there geting up to 12 and 14 footers well at that size they better have somthing on em.
ima start lookin around to see where some good spots are down here.
