Wow! Have you ever caught one on a rod and reel? I've caught a few that were maybe 10-20 lbs and they fought like hellions. I hooked a really big one off a dock at night, and fought it for about ten minutes but it broke the line. I got it to the surface, but it was dark and I only saw it jump once, so I couldn't really guess how much it weighed. My fishing rod was bent into a U shape when the line snapped. I was glad it broke though, as I had no idea what to do with it.
