For a general dry-fly search, the strongest matches are trout-focused surface patterns that cover the most common hatch situations. Big Y Fly Co Harrop's CDC Biot Dun PMD - Solitude - Mayfly Dry Fly is a very natural PMD dry for selective trout. Big Y Fly Co Harrop's CDC Biot Emerger BWO - Solitude - Mayfly Dry Fly is best when fish want Blue Winged Olive emergers in the film. Big Y Fly Co Harrop's CDC Biot Dun Trico - Solitude - Mayfly Dry Fly covers tiny, technical Trico surface feeding. For caddis, The Fly Crate Barbless CDC Caddis is a good slower-water option, while The Fly Crate Foam Caddis gives you a higher-floating, more durable dry.
Fish the mayfly dries with long leaders and light tippet for a dead-drift presentation. Use Big Y Fly Co Harrop's CDC Biot Emerger BWO - Solitude - Mayfly Dry Fly when trout are taking bugs just under or in the surface film. For caddis, add a little movement or a slight skate, especially with The Fly Crate Barbless CDC Caddis. The Fly Crate Foam Caddis is a better choice when you need extra float in rougher water or longer drifts.
Switch away from dry flies when trout stop looking up, the hatch is over, or fish are feeding deeper than the surface film. If the water is faster, windier, or more broken, move to a more buoyant caddis like The Fly Crate Foam Caddis or a pattern built for rougher water. If fish are ignoring duns, try an emerger such as Big Y Fly Co Harrop's CDC Biot Emerger BWO - Solitude - Mayfly Dry Fly instead.
