Well me being me I like to think a bit out of the box so some of these will be a bit different than most will likely post but I will post a picture with what kind of feather it is.
The tail is peacock sword fibers/feathers
The green grizzly one is a Schallapen (aka extra extra webby hackle) tip and regular grizzly is saddle hackle tip as well as the neck/ thorax on this one.
I tied this one for fun but would likely catch something... these are goose biots.
More peacock sword fibers
Tying tips:
For hackle to prep it I strip off the fibers at the tip for about 1/16" then I cut the tips off the next 1/16"-1/8" just so there is some stubble left on the quill of the feather and tie it in. The reason to leave some of the stubble is so it will lock the feather down so it doesn't slip as easy, giving the thread something to grab on to other than just the slick quill.
For peacock sword I tie it like marabou or any other fiber or hair on a standard jig, couple of loose wraps then tighten down some. You will want to be a bit gentle with this stuff as its pretty fragile compared to a lot of fibers but catching a big fish or two on a jig is worth it but for durability it wouldn't recommend it. Trout love peacock color though.
