Silver, thank you very much, the way you break everything down is so simple for me, i just need to do my research now and see what diameter i am using for both leader and tippet, and ill go from there. thank you.Well it gets more complicated if you are going to modify a leader.
In my post I noted that a standard commercial leader is most likely built on a 60/20/20 Ritz formula of 60 % butt, 20% transition, 20% tippet. This is the classic Charles Riz Tippet formula. Along with this formula is the understanding that the change in diameter from butt to transition to tippet MUST allow for the smooth transfer of the energy from one section to another. When a greater thicker segment of line that is thicker and of higher mass going a specific velocity becomes thinner, the law of the conservation of energy means that the thinner section MUST gain speed to preserve the kinetic energy. That is why the end of a bullwhip "cracks," That "crack" is the end of the bullwhip breaking the sound barrier.
This same conservation of energy MUST be maintained as the leader progressively thins.
So you can put a tippet ring at the end of the transition section BUT you are limited in the range of diameters of tippet that you can tie to this tippet ring. You should not step down any more than 1/3 the diameter of the section you are tying to. This was determined by Gary borger during his design of the Uni-body leader system.
For example, if the diameter of the transition section that tippet ring is tied to is .013", the thinnest tippet you should tie to the tippet ring is .009" diameter or 2X. If it the transition is .010", then you cannot go lower than .007" or 4X.
The way to figure out the minimum diameter is to double the diameter of the thicker section and divide by 3. So for the .010", 2 x .010 = .020: .020 /3 = .007 = 4X
So you must know the diameter of the transition section. And if need to step down in tippet size more than the 1/3 diameter restriction allows., tie in a 1 foot section of transition material with a lower diameter that allows you to tie in the thinner tippet.
You must also realize that tipper material and leader butt and transition material have different properties of stiffness that are designed for the job they do. You cannot simply use thicker tippet material for transition material.
