Larger fish do prefer large plugs. Big fish will spend the least amount of energy necessary to catch a meal . . . So, if you're after big salmon or lake trout, use the larger J-Plugs . But, remember that smaller fish often will not attack a large plug so the use of larger plugs, although great for big fish, may prevent you from catching smaller ones. Standard J-Plugs are popular because they are especially effective in deep water trolling situations, although, as indicated, they may be successfully used in medium or shallow water as well.
Extreme heat can deform a plug's shape and direct sunlight can cause the finish to fade.
Before placing your plug in the water, check the swivel chain dacron harness for wear and to ensure the knot is cinched tight. If the harness need replacing you may obtain one from a dealer. The dacron harness is 80-lb. The hooks that come with the harness are high quality, 4X strong and plated to resist corrosion. Following is a rundown on a few of the more popular finishes and what each represents and accomplishes in the water.
