So I ended up using the rosewood with basswood accent binding for the back edge and the ebony/basswood binding for the top trim. Wanted to use ebony for all, but only had 2 pieces, enough for top OR back. So I ordered more ebony from LMI, but when it came, I realized that they don't make it the same thickness anymore, and I'd already routed the rabet on both edges. So I used the rosewood binding I already had for the back, and the ebony for the top.
I think it looks fine and it'll probably sound a lot better too...:P
Here's how it looked going on:
Of course there's a lot more scraping and sanding to do, but it's going to look good.(and I've got enough ebony binding now to do the next guitar)
