Very nice tie, Alberto. I forgot who wrote the article, but it has been pointed out that the ears and eyes are probably more for the tier than the fish, so I tend to favor patterns that emphasize profile over details personally (e.g. Morrish Mouse or Master Splinter). One suggestion I would make is you might want to rethink your hook choice. I know I tend to like having as much gape as I can get away with, and deer hair mouse patterns tend to crowd classic streamer hooks a bit too much for my taste. For bass something like the TMC8089 is usually favored, but that can be too light for other species. I like the B10, and some favor even heavier hardware, but that might be something else to consider when you go into production, especially considering you are in an area where you might go after pike, musky, etc. Just a thought.
