ok so i went out flathead fishing last night and i had tons of missed hook sets. i was using live goldfish on the bottom with a 2 oz no-roll sinker(kept em down good) my first flathead i hooked into i got him all the way up to the bank and seen him it was probably the biggest flathead i would have gotten, but then right in my face, he spit out the hook and swam away. And other times i get a huge hit and i let the fish run for about 10 seconds before setting the hook, i flip my rod back and i can feel the weight of the fish, but then not even 15 seconds later my line goes limp and its gone. I'm using a 5/0 gama octo. is it possible that my hook size is too small and im not getting a good hookup? or what???
