Why are there so many different weights available for the same jig head that fits the same jig? The answer is “fall rate”
The example photo is a line-up of our Mega tube jig heads. 1.5 oz., 2 oz., 2.5 oz., and 3 oz. You can use this style head with a tube jig from 5.5 to 7 inches in length. The reason you would get all 4 head sizes is to vary the sink rate, or fall rate, of the lure, and it’s not necessarily dependent on how deep you’re fishing.
Fish will react differently to how rapidly or slowly a lure goes by them. A 3 oz. head in a 7-inch tube will fall very fast. This might cause the fish to “react” to the bait as it zooms past. The same tube with a 1.5 oz. head will drop slower, giving it a much more natural look. This presentation will really fool the fish into thinking it’s real food.
Sometimes fish want that reaction bite, and sometimes they want a more natural presentation, so it’s important to experiment with your jig head weight throughout the day (and different seasons) to get the right fall rate to match what the fish want.
Fall rate can apply to almost all types of jigs and jig heads and for almost all species of fish. It is a very important concept to keep in mind every time you fish a jig.
