100% sure it is not you hookup.
I learned a 'good bit' from him myself even though...... nevermind. I tied for some 20+ years off and on before i knew the difference of palmering or collars or tailing or whip finishes or hair stackers or etc. I was either wrapping it or letting it hang. Spent just as long not even understanding the difference between hackle & marabou, nor did i care, since my ugly ducklings caught fish. Back then, a feather was a feather was a feather. With the age of the internet forum, we can become fully edjumacated addicts in far less time. Bah...... who need rules. Tongue firmly in cheek.
Kidding aside, it looks well tied. Do you strip off one side of the feather fibers before you wrap them? Always conflicted in my head if i should or not. Usually do. I put some hackle collars on the swap jigs.
