I usually use heads, body, "steaks" or fillets. But in swift running water, I like to use whole headless shad bodies. I was fishing below an outlet and was fishing with an older fellow, I had a net and was getting the shad and he we were both using bodies, but he was catching 2 times as many fish as I was. I couldnt figure it out until he showed me what the called "the proper way to cut a body". Instead of cutting straight and making a 90 degree cut at the head, start at the head and make a 45-60 degree cut toward the anal fin. Then place your hook thru the portion of meat up by the head. The 60 degree cut will catch the water and make the piece of body look like it is swimming in running water. The 90 degree cut does not have hardly any action. Next time you are using Shad in running water check it out.
