SB - the cop car is a black and white spoon. Yes it's very effective but it's not the only spoon that will catch fish. Coyote's aren't the only spoon that will catch fish either. I have a variety of spoons in my tackle box and use them all. I think the best rule of thumb is to always make sure you and your buddy aren't fishing the same thing and change up if you aren't getting action. I have seen days where a cop car was killer and the very next day it wouldn't touch a fish and a green/chrome spoon would be killer. If the fish are thick and feeding you can get them with just a plain spoon but if not then a flasher will certainlly increase your odds. I always use 30 to 40 lb Maxima Ultragreen for leader. Good luck and remember if your not bouncing bottom occasionally for blackmouth you aren't in their neighborhood.
