Nymph
Olive Perdigon
Weighted competitive nymph
Trout · GraylingSubsurface
A tiny, hard-coated bead-head that sinks like a pebble — competition angler's secret, now everyone's. UV resin over a thread body in olive, ribbed with wire, down to size 18. Euro-nymph it in fast pocket water and it reaches the bottom before conventional nymphs finish thinking about it.
Fish this when
When you need to get deep fast — heavy current, deep pools, or anywhere tungsten density wins over finesse.
Why it works
Tungsten bead and slim dubbing body sink immediately. The orange tail and rib trigger without sacrificing depth.
