Straightened Hook @ DP ??

[flyfishaman]

I'm new here, And pretty new to Yak fishing. Mostly i'll throw fly's but went out yesterday in Dana Point, with trolling setup, picked up some sardines from the bait barge. I was in search of some hallies.
Fished Doheny beach w/ no luck, water had no vis, and just couldn't seem to get on any fish. Then paddled back north towards the Point. Started about 35 ft of water 200yds or so out from the wall and drifted back in. All of a sudden BAM, line started shooting out. so i let it take for a sec. then grabbed the rig and couldn't even turn the fish/monster . I was losing line by the second, finally full drag at about 35lbs test one good tug, and then nothing. Reeled in and i was left w/ no sardine and 2 hooks on the treble almost completely straightened out. It felt like i was attached to a U boat.
Any thoughts on what this was? I've caught a good size Leo this way but at least could turn the fish and fight it.
Just trying to feed the curiosity, any thoughts? Bat ray? Barry Sanders Underwater?

thanks,
paul
