Got this 80lb Yellowfin tuna on a blue Rainy's 5/0 popper on my Shimano Trevalla spin rod with 50lb Power Pro and 60lb fluro leader. It hit and the explosion looked like god dropped a bowling ball from heaven. Then it went down and drained half my spool. Got it to the boat in an hour and then it circled under the boat for another half hour. Finally got it gaffed and in the boat. My arms are still sore. I did save my back, so that is good. If it had been on my 12wt I would still be fighting it. Weather in Hawaii is unreal, like summer never ended.
