Sea-run browns do, of course, take the big stuff-bunny flies and marabou leeches, Woolly Buggers, Flashabuggers and Zonkers, muddlers and big Montana and Bitch Creek nymphs, fished down and dirty on the end of a Teeny sinking taper line or a small-diameter full sinking line that makes it easier to cast in the incessant Fuegian wind. At times, a sea-run trout will even pounce on an outsize Atlantic salmon bomber, a white Wulff, or other attractor dry flies skated on the surface. And the pancora, a local fly tied to imitate the ubiquitous Argentine freshwater crab, can also be deadly. It is true that Fuegian sea-runs are moody, spooky, and often exasperatingly finicky about taking a fly-any fly. But once you've suckered a 10-pound-plus fish with a size 14 Beadhead Hare's Ear (a Brassie or a Peacock or a Zug Bug will usually do just as well), you're hooked, so to speak.
