Help me decide on a neck for this guitar

[Agileguy]

I may be biased here, but I think you should go for an IRW neck with an Ebony board. I've got that combo on my D'avanzo (also with SS frets) and it's the best neck I've ever played, hands down. It's just such a fast neck because of the wood combos. And it sounds amazing too.

Mine is on a Mahogany body with a maple cap though, so I can't say how it'd sound on swamp ash (probably on the bright side) but you're pretty experienced in these matters.
