while fishing for grayling with my 3 wt it occurred to me that at any minute I could hook in to a king or a dog. They were swimming all around me. Luckily they seemed to show no interest in the woolly bugger I was slinging. This made me wonder if I could land a small dog on a 3wt. I've landed some good sized reds on the Kultina on a 5 wt. (was on a hunting trip when the first reds came through last year and all I had was my 5wt) Anyone who knows that river knows it is no slouch. So how light is too light? I haven't broken a rod yet but I love a good fight on light tackle.
