Tried to reply remotely a couple times but it didn't stick. . .
The pattern the Blackfin were crushing was a simple olive bunny strip fly, not the flying fish. This was the first time I've used it on the Tuna in that color. I can tell you that BIG American Red Snapper are real fond of that olive bunny fly. In fact the current Women's 10kg Red Snapper record was caught on that fly. I'll be using it more in that color for Tuna now as well.
