I once had about a 12 pound winter run hen slam me on the drift, I set the hook and nothing. Found out my leader had cut off on her teeth. I quickly tied a new one and slam again next cast, brought her in and my previous leader was still in her mouth too swallowed. Greedy pig.
I also once caught about a 5 pound steely with a full leader, about a 2 inch spin n glow, all attached to a big pyramid sinker already hooked in his mouth. Dragging that around and still couldn't resist hitting.
