LBH he lives in Texas, we call 3lbs bait down here ;D LOL
Man if your already catching fish you only need to make your bait bigger. I know you've been using 7in mag fluke, but get a 7in Lake Fork Tackle live magic shad. This bait is bigger and can be fish like a fluke. If that doesn't work try a 8in floating worm, these seem to produce at least one or two really nice fish when the bite is on.
