BTW, I have the AWII and I pack in a Wista, and I carry just about the same stuff as you. In addition, I get my spot meter, my filters, my cable release, and my dark cloth in the main compartment. (I don't have the 210 lens, I just have the 135 mounted on the camera and a Nikon 90 in a compartment).
I too have the camera at the bottom on one side. I can get some other little dodads in, like an extra lens for my walkaround camera (either a Nikon or a Mamiya 6) If I happen to bring that along. But we're in the same ballpark I think.
