Re: knots for thin tippet
For flies that are striped and paused, no doubt the Non-Slip Loop Knot is the best. Lefty did not invent it...he varied the direction of the final pass through the standing overhand knot and applied his name to that modification. However, using the 6X referred to (a size rarely used for streamer type flies) and for fixed knots for dry flies, I have forgone the clinch in favor of the Trileen Knot. It is stronger (in my experience) and importantly, will not slip to the side of the hook eye reducing frictional energy damage to the material encircling the eye and it preserves the correct attitude of tippet top fly.
