I usually drag a wooly bugger or a leech pattern when I am trolling for trout, but I like to mix it up often to see what happens. The other day, I was fishing for stocker rainbows at a local lake but my trusty leech wasn’t working very well so I replaced it with a stonefly nymph with white rubber legs. Within a few minutes, I started getting more hits with the stonefly. I think the legs are an important attractant for fish.
Stoneflies are usually used for moving water to imitate bugs like the salmon fly nymph. I don’t know a lot of people who fish it in stillwater but I am a big fan of it.
