Depends on what your going after. Ouy have to know your fishing hole, id say if you are fishing in a hole that you know there are some nasty logs and rocks down in em id go with som 30 pound triline big game. if there are not that many logs in the area i would go with some lighter line and set the drag and have some fun with it, you dont always have to horse em right in, besides the fight is half the fun.I have a rod with some 14 on it and then i have my flathead river rod and it has some 25 pound spiderwire super mono on it and that stuff is the greatest line that i have ever used in my life it is 25 pound test with only a 6 pound diameter
