One of the flies that I was using, (a hand tied fly) was causing my leader to twist up on each cast, almost like an old style telephone cord, which would then lead to a poor presentation of the fly, with curls of leader sitting on the water. I was baffled, because I had other flies that I tied at the same time, with all the same supplies, and the same technique, but just one had this issue.
After reading some items online I realized that I had made a mistake while tying the fly. This mistake however didn’t cause this issue in all the flies, most likely due to how compressed the hackle was, but just one in particular.
The mistake that I made was using one longer section of hackle, rather than two smaller ones. Since I wrapped the hackle only in one direction (clockwise) and didn’t add a second to counteract, it sent the fly spinning with each cast forward and back, twisting up the leader.
So remember to always tie two hackles on, each one going in the opposite direction for stable fly flight.
