A. Nice haul, better to be lucky than good any day.
B. That swivel is way too small for troll gear
C. They call it fighting a fish because it's you against the fish, I'm not sure why it's ok to pass it around. I'd work the hook through the side of it's face before I pass it off.
Easy Bro! He can fight the fish whatever way he wants. The swivel and clip held and he got that fish in the boat. So the swivel/clip is not way too small. Don't be a dick! Congrats on a great catch.
