9-Foot Dry Fly Leader, 4X

A 9 foot 2 inch dry fly leader that ends in 4X and is built to land a fly with a little slack for drag-free drifts. It starts with 20 inches of 15 lb and 20 inches of 12 lb Maxima Chameleon, steps through 8 inches of 8 lb Maxima and 8 inches of 8 lb Stren Gold, then 12 inches each of 2X, 3X and 4X, and finishes with an 18 inch 4X tippet. Every join is a triple surgeon's knot.

The knots

  • Triple surgeon's knot · 3 turns×7
    1. Lay the new line alongside the end of the leader so they overlap about six inches, the ends pointing opposite ways.
    2. Holding the two lines as one, tie an overhand knot, passing the whole new piece through the loop.
    3. Pass the same ends through the loop twice more, three times in all.
    4. Wet it and pull all four ends evenly to seat the knot. Trim the tags.

  • Improved clinch knot · 5 turns×1
    1. Pass the tippet through the hook eye and pull about five inches through.
    2. Wrap the tag around the standing line five to seven times.
    3. Pass the tag through the small loop just above the eye, then back through the large loop you just made.
    4. Wet it and pull the standing line so the wraps snug down against the eye. Trim the tag.

When and how to fish it

Use it on light rods for rising trout in flat water, riffles and seams where drag is the problem. Cast upstream or across and stop the rod softly so the fine front end falls with small waves of slack. The fly drifts free while the slack feeds out. Mend early and keep the fly line off the fish.

If the fly lands in a pile, the 18 inch tippet is too long for the fly or the wind. Trim it a few inches, and replace it with a fresh 18 inch piece of 4X once fly changes cut it short.

Common questions

  • Why are there two pieces of 4X?

    The 12 inch piece is part of the taper and the 18 inch piece is the tippet. Fly changes only eat into the tippet, so you can replace it without rebuilding the leader.

  • Why mix Maxima Chameleon and Stren Gold?

    The stiff Maxima in the butt carries the cast. The softer 8 lb Stren Gold in the middle helps the front end lie down with slack instead of landing straight.

  • Will it turn over big hoppers?

    Not well. The .015 inch butt is light, so wind-resistant flies land in a pile. It is built for mayflies, caddis and small terrestrials.

  • Can I fish it finer?

    Yes. Swap the 18 inch 4X tippet for 5X when fish are on small flies in clear, slow water.
