1/64 ounce jig heads in various colors, bobbers and slip floats, and a few jars of 1” Gulp minnows or live red worms will catch you fish always.
My favorite river rig is a #6 hook, a split shot, and a night crawler. I’ve caught Muskie on that.
These are just basic, easy and effective and a good place to start before you drop big money on lures.
And carp are a blast to catch. I call them mud trout. They’re naturalized here in North America, killing them won’t make a difference. They’re slowly being accepted as worthy gamefish here, as they are in Europe.
