The best style of weight when bottom bouncing a river bed is a must. Ideal for salmon, steelhead, and trout drift style fishing. Simply place a small piece of tubing on the line while rigging up and adjust tubing position to create desired leader length. Then slide a pencil lead stick into the tubing to hold it into place and you are ready to fish. Getting the tubing wet before putting the pencil lead in makes it much easier. They come in packs of 6 sticks. Two sizes available are .80 oz and 1.80 oz.
