@Bruce: there is a nice review of the 4x5" Titan pinhole camera. See:
You'll find some images from the Titan 4x5" there so you can check it for (lack off) sharpness yourself
I think that some of these images are very sharp (for pinhole) and not too soft. I suppose the 8x10" will be able to create the same sharpness.
