I was thinkin snakehead as the meanest too. I hear Bluefish are evil fish. Fisherman say you can watch their eyes and they are actually looking for an oppurtunity to bite you with those nasty teeth if you slip up. As for pulling strength and making blistering fast runs. The tint little spinner shark is insane in this department. They rarely get bigger than musky but wil pull a man in teh water if he isnt expecting that lazer fast run when its hooked.
