So, I've just taken the plunge and picked up a 10x8 Toyo monorail back. Waiting on it plus bellows to make it's way to me.

Does any one have any experience on the Toyo 810G - Are there any peculiarities with it, or is it just a scaled up 45G back?

also, looking for some advice on lenses for portrait (already have a 360mm Symmar f/5.6 but concerned it ma just be a little short)

Apologies for not using search as well as I could, but currently using phone, and have an agonisingly slow connection where I am at the moment.
