My brother fishes 3.5 swimshad in motor oil with gold and black flake in Canada and crushes the walleyes. Last time he went I gave him a extra bag of violet Canadian blue and silver halogram. The first part of the trip he got them on his primary color then on wed. they wouldn’t hit it anymore so he put the violet on and crushed them until he left. When he got back he said boy am I glade you gave me the violet ones.
