Perhaps the nickname is lost in translation, I can’t say I’ve ever met a “Banana”. This is a pretty interesting presentation for a fly tying video, and although my Spanish is non-existent, it’s pretty easy to follow. Matuka patterns are really great, but I tend to not tie them because they take a bit of extra time and patience. The best thing about them IMO is that you don’t need to worry about long wings getting fouled in the hook. One other thing to note, you may not want to put feathers in your mouth, if you need to have them damp, have a glass of water close by. Unless you prepared the feathers yourself, there could be any number of unsavory items in the material.
