So at least for the time being, aluminum will be reserved for the heaviest applications, while casting and inshore rods will remain limited to cork, EVA, Hypalon, rubber and plastic. And this fits a familiar pattern: As is true of most fishing gear, every choice reflects a trade-off. A rod used purely for casting light lures in inshore waters will be best off with a light butt and a plastic cap, just as long as you realize that plastic won’t last forever. You can improve longevity with rubber, but weight will also go up. A rod used for heavier action will benefit from the added leverage of a longer butt, but you’ll pay for that leverage when the butt gets caught in your shirt or jacket as you try to cast.
