Mad River Outfitters have created a page dedicated to Greg Senyo related fly tying materials. Pretty much everything he has designed/endorses/uses can be found here:

This is one-stop shopping if you are tying Greg Senyo style flies or just like using his name brand materials.
I am looking for a recipe for the Greg Sanyo Trout Parr fly. I assume you carry the materials. Look forward to hearing from you.
