Pairing for an Onyx

[paddyob]

Getting a female Onyx Perfc from my buddy.

I want to know what you would pair it with.

I would love a snowflake but too cheap to drop the cash for one.

So my realistic options are... Standard Perc, Standard OC, Black OC. Maybe a Darwin (can't recall for sure if this is the name of the one in my head-black with orange mouth area ?)

Any ideas?

I should add... Seeing I want to try cross breed, using somebody else's designer is kinda cheating. :P
