Mine was on the scale at Whitakers back in he early 90s or possibly late 80s and was certainly a football- think that football shape adds weight compared to the long more normal looking ones. Agree that one in the photo was a biggie and likely in the mid teens.
Biggest I ever saw was taken in the Vines bout 3 years ago -looked like a King when it came ashore, saw the crowd gathering went over for a peek and was shocked at the HUGE Brown.
I have Terrible luck with Browns - seek them and rarely catch- fun tryin though.
