I tied up some beadhead bird's nest and pheasant tails to try. I was able to land a couple of nice rainbows, and then lost the biggest brown I've ever seen. I had it to my hand and like a dummy I grabbed the tippet and snapped on a tooth.
Now highly motivated I went back the next night with net in hand. I landed a few rainbows, and then my biggest brown ever. A little smaller than the one the day before, bit still a nice fish. I estimate it at 22".
