If in doubt - overdress.
Thanks for steering me in the right direction! There are no book style cases for the Droid Razr. But, after looking at the Klever Case, I see they simply use a cheep protective case you can buy any where as the mounting system! You could glue, rivet or sew one in, and voila, custom fit, dead simple. The Klever Case is way to large, but the Book Book is perfect. This will definitely upstage any of my friends with their camouflage or neon cases!
I use a Pad & Quill case for mine. Looks like a book, quality is unbelievable:
