In cooking, they say a good dish starts with quality ingredients. Fly tying is very similar. Producing really high quality steelhead flies has a lot to do with selecting high quality feathers. In the case of MFC Ostrich for intruder flies, that selection work has been done for us already.
We've been carrying these for the past year or so and almost every pack I've seen in the shop since the day we brought them in has been of the highest quality. It's true Ostrich is not as stiff as Rhea feahers, but if you're looking for that high quality sparse intruder style pattern, these feathers are a must have.
