welcome to WebmasterWorld, spoofee!
I would avoid using underscores as word separators in urls.
I would also avoid mixed case in url paths as in your title slug.
you should concern yourself with url canonicalization when relying on a unique identifier in the url.
if an arbitrary title slug in the url yields a 200 OK you have a problem.
