Biggest flathead I ever caught was on the SA River. I was fishing for sunfish at the time and was throwing the smallest size Bomber Fat A on a 7'6" glass ultra light. It was fun getting him to the canoe gunwale, but when I did all I could do was think, "Now what?" Cats can be more predatorial than most folks give them credit for. Especially if conditions are not conducive for their normal tactics.
Glad you got into the target specie, KJ!
Bless the Lord, O my soul,
and all that is within me,
bless His Holy Name!
