What's your favorite handle pairing with Koa wood?

[NDGuy]

Ordering another custom knife using a nice Koa block and debating getting a split/bolster within the handle as well.

Any of you know of good pairings with Koa? I am thinking blackwood.

Another brass vote - looks awesome with koa. Or a brass spacer and ebony collar
