Francesco on my Korona I only have front tilt, back swing and back tilt, I have found these three movements all I need with 12x20. I rarely use the camera in vertical format, but in the few ocassions I have, the back swing was used as "tilt" to increase DOF. In it's normal panoramic configuration the front tilt is all I need and I rarely use back tilt.
Oh, sorry, I also have front rise, and I use this a lot, so whatever you do, get the front rise geared.
So to answer your question, if it was me I would have it done with front rise, front tilt, back swing and back tilt. Good luck!
