You're right about that, pardner,...mudfish is STRONG.
I caught one of those bums on my "genuine 4 pound test line, zebco 44, JC Higgins rod, brim fishing rig" and I thought I never would get rid of him.
On and on and on went the struggle...he looked like he was about 3 feet long, swimming around out there. Followed him with the electric motor and he just kept on pulling and making the drag "bzzzzzzzz".
I finally said "enough of this" and broke off the line.
