For trolling, use the cannonball weight to keep bait or lures in the strike zone and reduce line swing in current.
For egg/sinker rigs, let the weight slide on the line for a natural bait glide; these are good around weeds, rocks, and deeper water.
For flipping/pitching, pair tungsten weights with a pegging system like Siebert Outdoors LLC Smart Peg – 3 Pack to keep the bait compact and punch through cover.
