I went from an M6 to a Mamiya 645 Super and find the prints I'm making from the mamiya are quite 4x5 looking at 8x10 size, and the M6 were close to MF looking at 8x10 size. But when I went shooting with the M6 it was the cam around my neck and a hip bag, and the MF is a full on backpack with a lot of weight.
