The weightless rig can be a great rig for fishing with a variety of live and natural baits. When brook trout are in the shallows in lakes or ponds, you can flip out your favorite bait on a weightless rig and you will do well. In rivers and streams, you can get away with the weightless rig in the pools that offer some slack water. In the current, it’s not a great rig, but once you get out of the current, a well placed bait on a weightless rig is tough to beat.
