To my eyes, 11B is perfect - or at least as good as it can get (the only thing that hasn't been experimented with is making the outer "Star Wars" box outline rather than solid). All the 11s look professional to me, while all the 12s look amateur. I think this is because of the squashed top row. Differently scaled lettering is fine, but you shouldn't mess with the (ahem) aspect ratio. None of the OT logos do, not even the "Faces" ones. Not that they should be used as a reference, IMHO, since they are the SE logos.

So 11B is my choice. Ultimately, though, there is only one opinion that counts - Trooperman's.
