I now use a Chamonix for 4x5 and I highly recommend it. It's light weight but very rigid. I don't know how it compares to the Wista. You can't leave a lens on it when you fold it up. It will comfortably use the 90mm lens without a recessed panel or a bag bellows, and has reasonable movements even with the non universal bellows I have. The universal bellows has even more movements.
