If you mean dry flies, the strongest matches are the actual surface patterns: Harrop's CDC Biot Dun PMD - Solitude - Mayfly Dry Fly for selective trout on PMD hatches, Harrop's CDC Biot Emerger BWO - Solitude - Mayfly Dry Fly for fish taking BWOs in the film, and Snow Shoe Yellow Sallie - Solitude for visible, high-floating stonefly dries in broken water.
For carrying dries, Fulling Mill Hopper Box and Fulling Mill Tactical Box are practical storage picks because both are described as useful for dries and mixed trout patterns.
Switch away from dries when fish stop rising, the hatch is over, or you need to get deeper. In those cases, nymphs, emergers, or streamers will usually outfish a dry fly. If trout are refusing a dry on technical water, try an emerger first before moving to subsurface patterns.
