Since this won't be heard around the world, I'll tell you this:
Where you fished the Lost has tons of fish but is getting pounded by Ketchum guides/clients.
Since you've been there before, go down main st. in town until you reach a bridge. Fish downstream from the bridge and bring a wading staff. Stay below the high water mark unless you like western violence.
Silver's tough. Pray for wind for hoppers. If no wind, fish a unweighted dropper only 4" under a well presented dry.
Copper basin is stunning! Fish above wild horse creek road and you'll be rewarded with some great cutt' fishing. The smaller the water the more condensed the trout.
I've had 3 flats in Copper Basin in rental cars/suv's. 2 at once at 8800ft. elevation! Long story.
Hope this helps if you get back to paradise.
