This leader is purpose-built for the Truckee River (spanning Reno, NV and Truckee, CA). This is the approximate build that legendary guide Doug Ouellette describes on The Barbless Podcast #020 "Part 2-Truckee Fly Fishing Festival-Doug Ouellette-Czech Nymphing". You can listen to that episode here https://podcast.barbless.co/episodes/truckee-fly-fishing-festival-doug-oullette-czec-nymphing or on iTunes.
Doug describes his options for this leader (link: http://www.calvadaflyfishing.com/truckeeriverflyfishing.com/leaders) as the following:
"This is my choice of leader. It is lighter and more sensitive. If you want to fish the fly line outside the tip top, Options 3 and 4 are for an 11 or 10 1/2 foot rod. When using a 10 foot rod the first “STREN BLUE” or “MAXIMA CHAMELEON” section should be four feet, with a 9 foot rod the first “STREN BLUE ” or “MAXIMA CHAMELEON” section should be 3 feet."
