Matt, the Mamiya TLR cameras are great, I often use my C220 along side my Toyo 4x5. One problem you'll have in using the C33 as a wedding backup is no interchangeable backs, as changing film is slow. I use mine mainly with 220 film, as I've lost shots in fast changing light in the past when removing it from the tripod to change film. 220 film is harder to find now, but I still have around 60 rolls in the freezer. TLR's can be fiddly when used with polarisers and graduated ND filters for landscape photography, my interest, but there's ways around this. You'll enjoy using the C33.
