As the small Trout waters start to cool down after the summer this pattern really comes into its own.
This worm pattern can be fished at any depth on more-or-less any fly line once you work out where in the water column to present it, they will take it cast after cast.
The Partridge PWW is the hook of choice when I tie this pattern as it has a short shank and wide gape, giving you great strength and great hooking properties when landing large trout.
