A bass spinnerbait is a component lure, assembled from many different parts, a weighted head on a thin wire, a safety-pin frame, a hook, one or more blades of varying shapes and sizes, a pliable skirt, and assorted devises, spacer balls and swivels that hold everything together and allow spinnerbaits to work.
The most important component affecting the action of any spinnerbait is the blade . The size, shape and number of blades on a lure, dictate the level of flash and vibration it will produce, and should be the bass angler’s first consideration when selecting a spinnerbait for a specific fishing situation.
A long and slender willow-leaf blade will produce a lot of flash and is similar in profile with small baitfish such as shad and shiners. You should use willow-leaf blades in clear water, because a bass will feed by sight in such water clarity instead of by sound, and this is the most realistic looking blade style to be used in clear water. Willow-leaf blades are also well-suited to fishing submerged grass,because their elongated shape allows them to swim through fairly easily without getting snagged.
Colorado blades are rounded and heavily cupped. They produce incredible vibration, but not as much flash as the willow-leaf. Use a Colorado blade in muddying water and at night, when visibility is limited and bass will feed by homing in on the vibrations of moving prey, in this type of water clarity. The Colorado is also the best blade style to use when fishing sloping banks and ledges, since it the blade spins easily as the lure drops through the water column, creating flash and vibration.
Indiana blades are a compromise between the willow-leaf and Colorado blade. Indiana blades are a safe choice in stained water because it delivers a good balance of flash and vibration.
The length of a spinnerbaits wire arm is another factor to think about. A lure’s arm length, the distance from the line tie to the main blade, will greatly affect vibration level. A short arm, with a big Colorado blade, will throb hard. This is a good choice when visibility is low and bass must locate prey by sound rather than sight.
Maintaining a balance between the blade and arm is also necessary. A spinnerbait with an arm that’s too long or too short will roll onto its side during the retrieve. Avoid extremes, when you swap blades to customize the lure. The blade can’t be so large that it overpowers the arm, or so small that it doesn’t provide enough lift for the lure.
By manipulating the arm you can help facilitate a desired retrieve speed as well. If you want to bring the spinnerbait back quickly, a good strategy for triggering reaction strikes, push the arm down, bending it slightly toward the hook shank. When you want it to run more slowly to stay in the strike zone longer, pull the arm up.
All in all spinnerbaits have come a long way over the years. These type of baits are responsible for millions of bass catches each and every year across America.
As always good luck on your next trip to the lake and be safe.
