Epic morning for Trico's

What a great day for Trico's, arrived at 8:00 AM and only a few fish were working but they were like little pigs, come up and move either left or right all the while moving upstream then down and do it again, the trick is to guess which way they are going to go left or right and line it up- no refusals today! I used a dun but I just have no confidence in them and really never let it on very long. I used grey, olive and all black #24 spinners and they took them all. The pattern is simply 2 mirco fibbet tails split, thread body coated with head cement, clear Zelon spent wings (sparse is the key)beaver or mole fur around the wings, I like fur because it has short fibers). I had 4 fish landed over 17" and lost 5 really big fish from break offs bad leader knots or just too big to hold, most of these guys have been hooked before and know what to do and where to run to- brush. There was no less that 30 fish up in a 50 yard section more than enough to keep you busy. I even got a few 6" rainbows, we have no idea where they come from, natural reproduction? All this in Milesburg, PA on Bald Eagle! This will happen every day and the big guys will get really hard to hook, hell even some of the small guys near the road are dam hard now! As time passed more and more fish rose till about 11:00 AM then all I saw was a good amount of tan caddis and few fish up but this is not a good caddis area just too smooth of a surface to fish emergers, next time I'll go lower on the stream.
