It really depends on where one is fishing, and how big the cats are. For eating sized ones in still water with not much hangup, heavier bass tackle will do. For real brutes in current and nasty hangups, you almost can't go heavy enough, and of course there is everything in between. I like the lighter Ugly Tiger Sticks for good budget sticks for cats and salt inshore stuff, but there are a bunch of different things out there. The Shimano Bait runners are really nice reels, but a bit of $$. I usually fish 30 lb mono on conventional gear or heavy braid on spinning, and a heavy mono leader, mostly 50 lb on either. We are starting to get some real blues up these parts, and they are eating everything in sight.
