I'm sure that somewhere I read of reports from the first explorers to the new world of flats over 200lbs. I believe there are some out there that either haven't been hooked or who have been hooked and just couldn't be caught. I've read of blues over 400lbs way back when. Now thats not with modern scales but they must have been huge fish to garner that much weight. I don't think any of the current records will stand any length of time. Heck the blue cat record fell twice the last couple years. I think with more people fishing cats and more of them targeting big fish the record weights will continue to rise.
