Do you still have that back? If you want to sell it cheap, I'd be happy to glue it up and put it to use. I've taken to putting a few thin cross-grain reinforcement strips in addition to the back braces on brittle back woods, to help prevent cracks from starting and/or travelling. Great tip from Mr. Somogyi's book.
Honduran rosewood is one of my favorites. Heavy indeed, but one of my sets has the best tap tone of anything in my wood tower. It's quite dark colored for Honduran, which would tend to agree with Robert's observation on the darkness of rosewoods. I have some lighter colored sets that aren't quite as intense sounding, but still quite good. I used one on my current project, a small Torres inspired guitar, where the density is a good thing. The box makes a wonderful long ring when tapped, and sounds great with strings too Testing with the back free to vibrate versus damping it out, it definitely gives a nice tone color and "liveness" to the sound.
