The extra-long, ultra-thin leader is incredibly sensitive to the subtlest of grabs, and the two-tone indicator tippet tied to the front end has high contrast and is very easy to see. The leader is made up of 12ft of thin white, tapered butt section (going from .012" to .009"), with two feet of "sighter" material tied on to this. The leader then finishes with a RIO tippet ring so anglers can quickly and easily attach the tippet of their choice.
