I agree with Fishin is Life. I'll always fizz a fish that starts floating on it's side. The worst feeling I ever had was at Green River, there was a a good sized smallmouth floating on it's side and I didn't have a fizzing needle with me. It had been up to the point that it was bleeding and had a sun bleached spot on it's side. I couldn't fizz it, and couldn't save it. Worst feeling in the world by far! Since that day, I put 5 needles in my tackle box so that I'll always have one. The key to fizzing is to make sure that once the fish looses buoyancy, you take the needle out immediately, it'll go down and correct itself. Removing too much is just as bad as not removing enough.
