Ian's Brass Ass nymph

In this fly tying tutorial, I show a modified version of Ian Colin James' "Ian's Brass Ass." This is a featured fly on the Orvis website, and though originally tied for steelhead in the Great Lakes Region, this pattern has now become a popular one for Czech-nymph tactics, too. Being that there is a lot of weight to this fly helps it both get to the bottom quickly, and stay there longer. The fly also has a Copper John feel to it, undoubtedly due to the weight. I have varied it slightly, as mentioned in the video, and I encourage you to try your own variations, while maintaining the defining characteristics. This fly has caught steelhead, salmon, and all varieties of trout and grayling; open a spot in your box for Ian's Brass Ass.

Featured in this tutorial are the N203BL hooks from Allen Fly Fishing. These hooks are 2x heavy, which add to this pattern's weight and effectiveness. Check out those hooks and more at their website:

Long story longer

The Global FlyFisher has been online since the mid-90's and has been free to access for everybody since day one – and will stay free for as long as I run it.
But that doesn't mean that it's free to run.
It costs money to drive a large site like this.
