Take some 20lb Monofilament around 1.5 inches / 40mm in length and apply a flame to each end. This should create a "bobble" on each end which should act as a stop when tying in and prevent the mono from pulling out. The mono is going to be used to prevent the tail from wrapping around the hook.
Thread the mono through one of the twists of the body of the the FNF Predeator 9 about 3/4 inch / 20mm from the hook bend and catch in the remaining end of mono onto the hookshank on the opposite side of that done previously. This should have created a loop and hopefully is now acting as a stop to prevent the FNF material coming back on itself when cast. Apply a little superglue to each of the mono bobbles down each side of the hookshank and allow to dry.
Take a dumbell and catch in with thread just a short way from the eye, dab some superglue to the upper and lower parts of dumbell where the thread is securing it. Continue to use figure of eight wraps over and under the dumbell as shown in the photos.
Create a dubbing loop with the dubbing and wind up the hookshank including over/under the dumbell leaving the thread just behind it. Don't worry about neatness of the dubbing, we will brush the dubbing out at the end.
Take a partidge hackle and strip the fluff from the stem at the base of the feather. Take a set of hackle pliers or tweezers and catch the middle part of the festhers tip. Stroke the feather back from the tip with your fingers which should leave the tip clear for tying in.
Catch the feather's stem with hackle pliers and perform 2 or 3 wraps of the feather around the hookshank, each wrap should go in front of the previous and on each turn stroke the feather fibres backwards with your fingers so they aren't snagged with the next wrap. Secure the stem with thread and trim the waste stem.
