Ah yes, the 8x10. I have one in my arsenal, it's the heaviest thing I've ever trekked with. I have a Burke and James Commercial, they call it a field as it's not a monorail but it's also non folding, which plain sucks.

I can't go with the a mamiya 6 or 7, I need a mechanical rig. I like to know if something mechanically breaks it can be fixed... The same can't be said for electronic items.
