Ok, so I thought this would be easier than it has been. I have one collection, basically it's a blog post and I have a route setup for it in the routes file like so:

collections:
  updates: /update/{year}/{month}/{slug}

I want to have a second route like /pdf/{year}/{month}/{slug} that loads the same content from a different layout (in this case a stylesheet designed for PDF printing).

I've checked the docs here and watched the screencast. What I'm doing isn't working.

routes:
  /pdf/{year}/{month}/{slug}:
    layout: newsletter
    load: /update/{year}/{month}/{slug}

Any help would be appreciated.
