Well, I can only speak to the 7x17, but it would seem to me that much more managable, both in the field and darkroom. The 7x17 for me anyway is certainly 'doable' in the field (albeit not a 'backpacking' camera, although some probably do). I have a very small darkrroom and with seed trays its very managable. You can check out my website www.scottpetersphotography.com, link below for an idea on the panoramic format in that size. The 7x17 is nice on the wall for sure, and also, a size that I think is nice for holding in your hands for personal viewing.
