Presentation & control
Drift, depth, speed and slack: what the fly does once it is on the water.
Mending the Line
A mend is a small correction with a large effect: a flick of slack thrown into the line to counteract the current's pull on it, keeping the fly travelling at the speed of the water around it rather than the speed the current on your line dictates.
Achieving a Drag-Free Drift
Drag is the fly moving unnaturally against the current — and it is the single most common reason a good fly is refused.
Presentation Casts
A reach, a curve, a pile, a tuck — these aren't tricks, they're specific answers to specific problems a standard cast can't solve.
Managing Slack and Contact
Too much slack and you never feel the take; too little and the fly drags before it reaches the fish. Every method asks for a different balance.
Controlling Fishing Depth
Depth is usually the biggest variable in whether a fly gets eaten, bigger than pattern, bigger than colour.
Controlling Fly Speed
The same fly fished fast and fished slow can produce entirely different results from the same fish on the same day.
The Hang
A pause at the end of a retrieve or a drift, flies held beneath the rod tip for a few deliberate seconds — on the days it suits, it accounts for a disproportionate share of the takes.
