An ultralight rig can be a compass, pointing directly at the highest concentrations of fish. The same principle works for most species, with heavier gear. The principle is to play on the aggressive characteristics of fish that are grouped. Groups get competitive, and aggressive lures will make the most competitive specimens strike. Or at least follow! That's the key. Wear polarized sunglasses and watch closely when retrieving the smallest lures in your box—those Yo-Zuri Snap Beans, Rebel Cat'r Crawlers, and tiny floating Rapalas. Crappies and bluegills almost always follow in a pack after a tiny lure intercepts the edge of a big group. If they won't bite the lure, switch to smaller jigs and bait under a float or pitch tiny tubes and grubs. The best ultralight rods are 7 feet long, have a moderately fast action, and are rated to protect 2-pound line. Spool them with 4- to 6-pound braided line, and tie in a 3- to 4-foot 4-pound fluorocarbon leader, to make the longest possible casts, covering more water faster. Remember: Panfish are always grouped. The idea is finding groups quick, so work the lure slowly all the way back to the boat.
