Use Straight 'n' Soft tapered leaders. They are the only leaders on the market that don't coil. They aren't shiny and they lay dead straight. They are a dull matt grey colour at the butt section and clear at the front.
Typical dry fly setup
- Stuart Crofts #4 Float
- No tool nail knot leader to fly line or whip a loop

Use Hybrid. Designed for World competitors, it's fluorocarbon coated mono that doesn't get weaker when wet. Wet knot strength is the variable competitors look for.
