Shaping the Spun Deer Hair

I'm using scissors to shape the spun deer hair head of a Muddler Minnow. I love fishing the Muddler Minnow with a small dropper of about 15" with a Pheasant Tail Nymph. The dropper is tied at the hook bend of the Muddler. The Muddler acts like a strike indicator and sometimes attracts a huge trout who passes up the relatively tiny Pheasant Tail Nymph. I found I could tie the dropper to the bend using a Duncan loop, which can be loosened easily.
