So basically there's no good reason they don't offer plain maple. Trust me I love a good figured top too, my CU24 semi-hollow has an awesome 10 top, but the classic translucent plain maple top look would be awesome to see. Mahogany/korina doesn't finish in the same way so that doesn't really count.
It is what it is, I guess. I'm just surprised that there's literally 0 examples of plain maple PRS. I don't think they're inferior to figured tops, just a different, slightly more natural look.
