The Dolly Llama is one of the hottest flies in Alaska! A heavy conehead makes the fly dip and dive when stripped and the trailing hook ensures solid hook ups.
Use the #2 for most applications in Alaska. If you are targeting big trout, the #4 has all the size & motion of the #2 but with a trout-friendly hook. The #6 is a great small stream searching pattern and Lower 48 and South America trout fly.
