One that I have had my hands on? I have caught up to about a 5-6 lbs largemouth. Biggest smallie that I have touched is about 3 1/2 lbs but had one that I got to the bank that would have gone over 5 easy; I just got to see it as it flipped off on the bank and back in to the water. Have hooked bass bigger but never got them to boat usaully throw the hook.
