Went fishing last night and had a few bits on a wooly bugger, the most frustrating one being during the retrieve and I felt a pretty solid Whack! I paused for a second, pretty sure I set the hook on the retrieve. When I saw a good-size silver flash in the water I raised the rod to start the fight. However, one good tug and he was gone.
I brought the line in... and no bugger. It looked like it had untied, not snapped. There was a tight curl at the end that I think was where the knot had been. I had been using a Frog Hair leader, which I was told had some stretch to it unlike most fluoro leaders, and that I didn't need to leave much of a tag end. Is it likely that it untied? I was using an Improved Clinch Knot, with maybe 4 loops around the main line while tying.
I'm thinking I either need more loops around the main line, a longer tag end (I probably about 2mm max), or I didn't raise the rod fast enough and let him yank on it while I was holding the line in my line hand and didn't realize how much pressure I had on the fish. Any ideas?
