My opinion is....you NEED the wing AND the fascia to make the look just right.
Obviously, opinions vary....to some the wing/fascia is just too much. I think it all depends on the whole package, and (if I do say so myself) my car definitely had the WHOLE package.
I've seen cars with the wing that just didn't flow for some reason.
Get Joel's at $1K.....thats a good deal. ABSOLUTELY NO offense to Joel, honest.......but plan to spend a little $$ to make it perfect. I bought mine for about a grand, it had some tiny cracks, no big deal. My body guy made it look flawless (that pic above was taken at his shop after installing the fascia).
