ID this fish based on how it fights?

At the fishing derby in SC yesterday, I hooked into something heavy---definitely the biggest thing I've ever had on the end of my line. It broke off after about 20 minutes, before I could see it. I suspect it was a shark, since a couple of them (smooth-hound, I believe they said...) were caught nearby, and I also hooked something that sliced thru my 30# mono leader just a few minutes before.

Here's a brief video of the first minute or so after the fish hit:



The way it fought was very distinctive, and unlike anything else I've caught. It's probably not noticeable from the video, but usually when it made a run, there was a strange high frequency component, almost like catching a mackerel on light tackle, but with a heavy weight behind it. There were no acrobatics or long horizontal runs, so I don't think it was a thresher. It definitely did not fight like a halibut, ray, lingcod, etc.

GWS, Seal, Big Jim,??? probably never know.

The hardest part is not knowing. I've been there!

Definitely a BFT!! 

Humboldt Squid ....how deep were you?

Doubtful it was a Humboldt.

A baby wheel for sure.

A baby wheel for sure.

    Never gets old!

Couldn't have been Big Jim he was running in SF ,maybe Andy though

Andy doesn't go out that far.

That was the shark rolling on you.

Had to be a Merman... Only logical guess.
