No doubt, there are a lot of "fly fishermen" that are snaggers. Many don't realize that's what they're doing, but most of them do. Those guys on the Kalama, for the most part, know exactly what they're doing. The only reason to attach 10-12 feet of leader material to a 15-ft. section of T-14 is to leave a suspended length of line throughout the water column that comes down toward the fish from above while the sinktip is stripped in. Using a tiny, tiny fly at the end of this setup is only beneficial in that the fish can't easily see the hook coming at them.

If you ask the majority of those guys where else they like to fly fish, they will tell you that is the only fishery they take part in with a fly rod, and only because other gear is illegal that time of year. In other words, those guys aren't really fly fishers (although some of them are impressive roll casters - I guess if you do something enough, you will eventually get good at it).
