Hey Vicrider, So in response to your question I have no idea 🤷♂️. I typically back the bend of the hook in as well. I recently bought that fly box (8$) so I thought it was a steal. That being said all of my other boxes just have the slit in them not the small triangular part, I’m guessing they are so there’s more room for the hook point? Guess it was oversight as I was rushing to the post office before work. I took some of these flies down to a nearby pond and racked up more bluegill than I could count so I hope crappie like them just as much!
I considered using a dubbing loop but with some persistence and 10 chubby sausage fingers I was able to get what I hope is a tight enough dub on there. Happy Fishing!!
