  • An 8-foot leader built on a smooth, gradual taper from .018" butt to .006" tip. It's designed for light-touch presentations to panfish in still water, where a gentle cast and a forgiving taper help you land small flies without breaking off. There's also a 4X variation; see the questions below.

  • A 7.5-foot, 5X leader built on a smooth taper from .017" butt to .006" tip. It's designed to turn over small, light flies cleanly and land panfish without excess splash or disturbance. The formula suits 3 to 5 weight rods and works well where stealth and delicate presentation matter.

  • A 6-foot (72 inch) tapered leader for panfish on a 4-6 wt rod, built to turn over small poppers and float small dries. It steps from a 22 inch .019 butt through .017, .015, .012 and .010 to 15 inches of 3X tippet at .008. The stout butt handles the air resistance of a popper, and 3X is strong enough for bluegill and crappie around weeds.
