Fished the Gunnison one spring during some excellent caddis hatches, several dozen fish a day on dries fished against the banks, river pretty much to myself.

And then one day there were salmonflies everywhere. So I dug out that box, caught a bunch of fish, had fun.

Next day, showed up to the river, people everywhere. Word had got out. And they were all fishing salmonflies, and nobody was catching fish on them. As trout rose to caddis around them. In the spaces between other anglers, I fished the same caddis I had been using two days prior, and was catching fish just fine.

If the trout want to eat caddis, feed them caddis. If not, use what they want to eat. I try not to make it any harder than that.
