There's actually not a huge amount of difference except for the dark cloth. I have an incredibly light rig -- a Phillips Explorer with a small wide-angle dagor, which works on a Gitzo reporter, and I carried my film holders in an elegant leather hunting bag I bought in Lucca. I didn't take a single cab in three months -- all metro, bus or foot. Would love to go to Poland -- those eastern European countries fascinate me. In April I am planning to go to Ljubljana to check out the work of the great architect and urbanist Joze Plecnik. He also did interesting stuff in Prague. No more view camera -- the Leica Monochrom is plenty good enough for me.
Carried 8X & 4X for years in the States. The 120 was just easier in the Eastern European Countries .. but you still run out of film though.

And I wore a vest with 120 film across the front -- looked like I was carry shotgun shells through this little hamlets

My friend worked 5X7 in Iceland > had to Express film over from New York B&H

I have 20 years of shooting architecture /people in Europe .. did work in Ljubljana.

Also 3 nice visits to Riga .. I went before the Wall came down -- so many places were still in tact --almost post WW II. Much too crowded now -- especially with a tripod.
