Here's a little more on hackle tip wings that might help some who may be having trouble selecting and setting in the wings. It is presented for tying a streamer wing but the basic technique applies for other styles of flies too. Just one opinion but I do not strip the tie in area for hackle tip wings, veilings (sometimes) and, toppings. I trim the barbs with scissors and this helps in two ways. First, there is a little more holding in the wing/topping/etc with the stubble and second, the stubble helps to keep the part from rolling when tying it in.
