Thanks, Billy, as I probably would have never seen this posting, seeing how I primarily monitor the Lakes forum.paging @Starman77
I've read that boatmen sometimes "carry" a bubble of air with them to breathe from. If the fish are taking your fly for a water boatmen, I wonder if the flash in the flashback mimics that shiny bubble.Yesterday Krusty and I fished a Zipper Lips lake and caught an enormous number of fish. He fished out of a high speed pedal kayak and I used a dead slow float tube. He was able to fish the entire lake and I pretty much confined myself to one rather shallow end of the lake. We were both successful but used different methods to hook fish. Now with a fly rod in his hand instead of a paddle Krusty's catch rate has at least doubled as he has instant contact with the fish.
I fished mostly slow and shallow using a floating line with a clear 15' intermediate sink tip. Two flies that produced the best were a boatman pattern and a flashback halfback that I believe is often taken for a boatman. After breaking off my best boatman I tied on a fresh halfback and continued to hook fish. Best fish of the day was just a bit over 20'' and we each caught just one of that size. I left the halfback on until it was time to leave and it was still catching fish as I approached the takeout. It hardly resembled a fly by then, the tail had a single fiber left and all of the legs had been broken off, the only thing remaining intact was the mylar flashback and I assume that was the trigger that was still attracting fish.
I see some boatmen that are black with a tan belly and others that are mostly tan. Yesterday I saw some take flight right under my rod tip that were actually white, I had never seen that before. Tie them in several colors to match the local menu. I fish them with short fast strips interspersed with pauses, takes are usually hard.
