Yes, I've got the History Channel doc, but I tend not to use commentary from people if they weren't directly involved in the creation/production of the film.
As for the grappling hook, unless DWR comes up with some evidence that it existed in the lost cut, I am afraid I won't be perpetuating the myth. Logic tells me that by now we would have seen this footage if it existed. I am still open to suggestion but I won't be including a mention in 'Star Wars Begins'. Sorry if that disappoints you
