The best I have found is chartreuse, second best is tied between Fo. red and orange. If you haven't tried this stuff before, heres a little tip. Tie up a 2 or 4 pound leader about 36" long with a small hook and a bullet weight, put a short piece of round toothpick in the bullet weight, this will allow you to float the bait off the bottom anywhere along the leader. Powerbait is a floating bait. Then watch your line more than the pole tip, if all of a sudden the line becomes real slack the fish is mouthing the bait and swimming towards you, set the hook. In this manner you will probably only hook it in the lip. Good Luck
