This Sempermouse has many rigorous hours of R&D that went into its creation. Steve (Fellow AvidMax Fly Guru) and I have been working on this fly for over a year and are happy to finally share it. Thank you to Semperfli for providing us with such a cool material to utilize! Semperfli Wabbit is a super unique material that performs great and lasts fish after fish. It has excellent movement, dries/sheds water very quickly, and is super tyer friendly. In order to get this fly to have the right action and floatability, the 6mm foam is very necessary. Using anything less will lead to a scuba diving mouse pattern (which also works on the right rivers), which does not allow the mouse to swim frantically on the surface. We like it in a couple of different combinations, but the Fox Squirrel is the go-to color. If you have never fished a mouse pattern for trout, you need to! It can be some of the most exciting “dry fly” fishing you will ever do.
