Perhaps the biggest stumbling block when nymphing is actually determining a taking trout. Speaking personally, my introduction to fly-fishing involved traditional wet flies. Moving flies quickly now, any interest from trout registered as a positive tug on the line. However, trout feeding on bugs and nymphs (especially buzzer pupae) rarely need to pounce on their prey. Instead, they sidle up to inhale any unfortunate nymphs. Because our retrieve is painfully slow now, takes rarely register as an arm-wrenching pull. Given this, we need to rely on a visual prompt rather than feel! Some claim to see the tip of their fly line or leader disappear down some imaginary hole. However, given wave action and poor light in many circumstances, this is not a school of thought I subscribe to. Instead, your focus is best trained on the mid-section of your fly line, or where it enters the water off the rod tip. Any bowing in the line, caused by a crosswind, will slide away when a fish takes hold. Watching the line at your rod tip is arguably better again. The line usually lifts like a coarse angler’s swing tip to signal a take (diagram 4). Furthermore, on ultraslow retrieves any memory in a fly line results in open coils that snake out over the water. These should be closely observed as any straightening here points to a taking fish.
