On tippet attachment methods: Although I am using different knots to accomplish the same thing, I like the Oni-Long-Loop attachment method because the long loop creates a Transition Doubled Tippet Section of line that gives better accuracy and less hinging of the smaller diameter tippet material to the much larger Line diameter of the T-lines, whether they are Level or Tapered lines. And who among us can compete with Oni’s casting accuracy? Here is a Video showing the knots that Oni Uses:
To keep a constant and consistent line length, I tie Perfection Loops at both ends of the line length I want, using a Girth-Hitch Loop to connect to the lilian on the rod end, and a Loop-To-Loop knot to connect the Tippet to the Line on the fly end. When you need to replace the tippet, you just cut one leg of the tippet loop next to the loop-to-loop knot and pull the old tippet away. The weight and resistance of the double loop and the Loop-to-Loop Knot setup provides a Sea Anchor in the water, the resistance of which helps you to hold more line up and off of the water in your presentations. Give it a try and see what you think.
Another advantage yo using a Perfection Loop at the end of your T-line is that it gives you a very effective release point for doing the Bow-And-Arrow or Sling-Shot Cast. Usually, when doing the Bow-And-Arrow Cast, you are not fishing a very long tippet - usually less than 3 feet. So you just let the tippet and fly safely hang straight down from the Perfection Loop, and when you release the line to make your cast, everything automatically comes up and into line with positive results. Again, try it to see if it is not better than what you have done in the past.
