How to Rig It

Fish the Jig Copper John as the point fly on a euro rig — the slotted tungsten bead and 60-degree jig hook keep it riding hook-point-up to reduce snags.

How to Present It

Tight-line drift near the bottom with constant contact and short controlled lifts at the end of the seam.

Why It Works

It combines the time-tested silhouette of the Copper John with the sink rate and snag resistance modern euro nymphing demands.

History

Jig conversions of classic nymphs became a centerpiece of competition fishing in the 2010s, and now define how most modern trout anglers fish weighted patterns.

Pro Tip

Always check that the bead is sized correctly for the hook — under-bead and the fly drifts wrong, over-bead and it tumbles unnaturally.
