I like these flies.
However, I have two suggestions for the spey version: 1) use a larger size body hackle since spey fly hackle should extend and flow beyond the hook's bend; and 2) tie the wing in so that it covers a bit more of the sides of the body.
If you look at Pastortd's recently posted fly, you will see that he tied the wing in so that it is spread out a bit and is less vertical. This is what I mean by tying in the wing so it covers more of the body. Aslo, his hackle is longer than the hook's bend giving his fly a different look than your spey version. This is how spey hackle should look, in fact, it is "the distinguising" feature of a spey fly.
