I'm heading to the Boulder Mountains tomorrow and looking forward to catching fish on mouse patterns. I added a little glow in the dark foam to these flies. I think it will make things a little easier at night. I'll report back soon!
This is a modified "Matt Hynes Mouse". I really like this fly and he has a great tutorial on how to tie it. I had the hardest time spinning hair until I viewed his other tutorial on spinning hair. I used GSP 100 thread and didn't have any issues breaking the thread, but I cut the foam and hair a couple times from too much pressure.
