Good morning, Kevin;
I have not been out too often with them, but I do have an F and an F1. I use a fairly large Gregory pack, because that is one that I have, and the thing does fit me. I take mine off the rail, and I wrap the standards and bellows with a Velcro strap and then a cloth wrap around them. All of the other parts (usually 2 lenses on boards, et cetera) also get wrapped. The film holders in plastic bags are in a bag that holds 8 of them. The drape is used as padding in the pack. The tripod head goes in the pack. The tripod is either strapped onto the pack, or it is carried separately. The rest of my stuff that I might need if I am kept out overnight is also in the pack. Yes, it does weigh something. So far, I have not really needed more than 5 of my film holders.
Enjoy; Ralph, Latte Land, Washington
