For me, the answer recently changed from Yes to Maybe.
I have landed 5 largemouth over 7.5 lbs, by the time they reach that size, their heads are noticeably different (larger). I had hooked & lost fish in the 4 to 5 lb range, but never lost one that made your jaw drop when they broke the water. My luck with landing any fish that possibly could break my PB is most likely rooted in that 98% of my fishing is on a lake with very little cover that the big ones can break you off on. That was until last month when I made a trip back east, the first leg which landed me in Georgia.
I was lucky to get a chance to fish two small private lakes, both about 5 acres. The first one was heavily wooded, so I was using 65lb braid to horse the fish out of cover. The 2nd one had much less timber and I was told by the owner that it wasn't fished much & that the bass in it were stunted. Therefore, my first cast was with a ZMan TRD, which resulted in an 11" bass. Got bit on the 2nd cast, but missed him, caught replicas of the 1st fish on the 3rd & 4th cast. I had 8 lb line on so the smaller fish still put up a fun fight. My 5th cast resulted in bite, I set the hook and it barely budged. My first thought was "Please be a bass" and about 10 seconds later, she wallowed up to the surface proving she was. Her head was every bit as big as any of my previous big fish, but I didn't get a good look at her frame. I continued the fight, but she decided to head over to the only log in the water within 40 feet. I couldn't stop her, she peeled off drag and got there. I was fishing from shore, so my options were limited, I kept pressure on her & tried to guide her out. She finally ended up breaking off my leader against the wood, so I never found out if she was over that 8lb 6oz mark that is my PB. I fished that lake an hour more that day and for about 90 minutes the next day, landing over 40 bass & a dozen bluegill the size of ones face, but no hawgs. She was definitely "Queen of the Pond" & now she has a TRD as a lip ring.
So what is your answer to the question,Yes, No or Maybe?
