In 4x5, I'd far rather carry my Sinar Norma monorail than any folder. It's faster to use and can handle just about anything bellows-wise, or with
respect to extreme focal lengths. But for airline travel or long-haul backpacking, it's just too bulky. That's why I also own a petite little Ebony
folder. But in 8x10, I only use a Phillips folder, simply because nearly all my shooting in this format involves dayhiking with a pack, and a monorail
that large would be rather cumbersome.
