Kastmasters amaze me. A dang slice of bare metal, and fish often love 'em.
Quick story: I'm pretty new to trout & didn't have much in my tackle box last August up at Clear Lake on the McKenzie. I'm in a float tube during the evening bite, fish literally popping up to grab bugs off the surface everywhere around me. Rooster Tail strikes out, power bait strikes out, salmon eggs get nothing. Just before sundown I find my old, OLD silver Kastmaster with a slightly rusted hook and figure, 'what the hey' so I tie it on. In 10 minutes I had 3 hard strikes, none of which hooked because the hooks were so dull. Back at camp I pull out an old hook file and sharpen the points up, hit the water first thing the next morning and hook a nice little 9" native Rainbow. I nicknamed him "Brunch"
Oh, and I just bought a new silver/blue Kastmaster
