I don't mean to sound rude but for the love of god, don't name your kid kaspar.
I mean, unless you're a white couple living in East LA and know a joker, lady gigglez, smilez and a riddla, then PLEASE PLEASE PLEASE don't name your kid kaspar, he'll get made fun of so badly.
As for my opinion on the others, with the exception of louisa-may, they're all pretty damn good.
My personal favorite combo would be Isabella Jaymes though.
Also the Nicholas Gene combo is pretty cool.
edit: but that's just my two cents.
