Hi guys, just got back from a day out in Seoul. Stopped by the River Fly Shop which is ran by a one of the local guides. Described the video and he pulled it up on his computer quickly. He knows the guy in the video and where he was fishing. I asked him what fly he was using and he said, "bread". He went on to say that people feed these carp bread so the carp FF guys use flies that resemble pieces of bread. Makes sense. He quickly obliged me by tying a couple of the "Bread" flies. See below.
The Bread Flies
Pretty strange but it makes complete sense to tie flies that resemble the bread hatch.
Anyways, it was a great day in Korea and me and my daughter had a great lunch.
