I must say that since BeeMan raised such a stink, I've turned my awareness from the 16-35L-II towards the Zeiss 21mm & Leica 19mm. I am not too concerned with focal length over 24mm, and will value wide open resolution for the hand-held. The 16-35mm-II will have some advantages also, I might try one as well.
Don't suppose anyone around Boulder, Colorado has those fixed lenses to show me?
