Cat Fish Info
The topic can get a lot deeper but that should get you started for now. If you have more questions pop into the catfish section and we can go from there.
I mostly fish for flatheads in a lake with very little current and no real snags to worry about. I use medium/heavy baitcasting and spinning rigs with 20# Berkeley big game mono.
I use slip-sinker rigs and 3-way rigs with 1-3 oz weights. I use large inline circle hooks and large live and cut-bait. I highly recommend inline circle hooks no matter what type and size fish you plan to target.
For channel cats and bullheads, cut-bait and stink bait seem to be the preferred method. Sonny's seems to be the preferred brand.
If you plan to shore-fish, you'll need good strong rod-holders. I made my own with pvc pipe attached to a piece of steel rod. These are strong enough to hold a fish until I can get to the rod.
Let us know what you plan to target and where, and you'll probably get some more specific information. Good luck!
