Digital BW, The Print

So I think I'm going to frame with 8-ply AlphaRag from Bainbridge which comes in both "Pure White" and "Pearl White".  My prints are Eboni on PA Generations Alise Museum (aka Natural).  I'm guessing the Pearl White is going to be the best match for this non-OBA paper and slight warmness of Eboni?  Anyone have experience or a guess?

I sadly can't seem to find any places in town with 8 ply samples, and while FrameDestination has a cheap $2 sample kit, after shipping it is more like $10...

Thanks!
