Neil,

Good article. My standard leader for the Clark Fork is a 3X Rio tapered mono leader with 3X fluorocarbon tippet for the first fly and 4X for the dropper or second fly. If I run out of 3X, a 2X will work just as well. On smaller dry flies I do go down to a 4X, seldom 5X. But then the Clark Fork produces some rather large trout, as does the Missouri, and I like to get the fish in fairly fast so I don't want to use real thin leaders.
