" a wide array."
Makes my teeth itch. My Oxford CD has strictly military meanings and Atomica says its sometimes an elaborate arrangement.

The Concise OED that lives in my study has considerably more meanings that that, both as a verb and as a noun.
"To dress or adorn with display" v.t. or "an imposing or well-ordered series of persons or things" n

So "a wide array" doesn't sound too bad to me!
