I like using the Gill Pill when fishing shallow water. My preference is for bright colors and the smaller sizes. When I fish deeper water (greater than 10 feet) I do not use the Gill Pill. The jig is too light and it takes a bit of time to travel to the depths I want it to reach. Sometimes when you have small gills in the shallow depths they swipe your bait before you get a chance to get it down. In those situations I switch over to a fiska tungston jig.
