I lost one well over 10 pounds a few years ago at Millwood Lake in Arkansas on a white fluke. My reel kept messing up and I had to stop and fix it in the middle of a cast. Well, after I got it all straightened out, I picked the rod back up and saw a large bass inhale my fluke. Well, I began pulling it in and it ran around a stump and started thrashing, and needless to say, it came off. :'( That's not a good feeling to have.
and another time, I lost another one at Millwood that was probably between 10 and 12 pounds. I was fishing with my father in a tournament in the early spring when I lost this one. Dad kept having a fish hit at his lizard on the same tree every time we threw at it. Well, I threw past him to follow him up in case it missed his lizard again. Well this worked great, except for the fish making a furious ran at the surface and throwing the hook as our jaws dropped. I have yet to catch a 10 pounder, but I have caught a 9.
