I've read throug quite a few of the lightweight equipment and hiking threads, but I just wanted to see if there are any "ultralight" hikers/backpackers out there who shoot large format and what they use.

I do a bit of hiking in the mountains and through forests and occasionally take my Pentax 6x7 which is a beast and very heavy. I used to have a huge box with a heavy Toyo monorail which was even worse. Looking to get back into LF shooting while out hiking but interested in the concept of doing this in a ultralight fashion.

What do you use? What compromises have you made to keep things extra, extra light? Would love to hear some creative solutions.
