I should probably switch to tying coho flies since the chance of tuna fishing again this year is somewhere between slim and none. Just can't seem to stop messing with tuna flies. This version is tied on a 3/0 U-401 using Fishair blended with EP fiber at about a 60/40 mix. The top wing is a mix of Angel Hair in Baitfish, King Fisher Blue, Purple, and capped with Black Light. Also attached some parallel strands of fine lateral scale to the inside of the gill plates before tying them down. Seems to transition the flash at the head into the body better. The color transition at the head was done with fine point sharpies in blue, purple, and navy applied on successive coats of UV.
