Most of our fishing here is wet flys. For a fast deep sinking leader Berkley "Transition Gold/Red" 4# test fluorocarbon has proven to be the best to date. To avoid the line twist you get when swinging wet flys I have been adding a small swivel to the tippet end



When I do get the chance to fish dry flys I use Uni 6/0 and float it.

I understand your method and hope to learn a little more of it when Kaboom1 and I get out your way this September.
