I've added them! It's true they weren't on the list, but I knew about them from @CarlosBI. Seems like a complicated copy of Doval, with two separate optional adjusters... need to get a decent internet connection to see their french videos to understand how they work.
No clue about the circular to non-circular relation, just wrote about my experience some post earlier... went from 50x34 circular to 52x36 Doval and everything was still the same in terms of climbing and fast flats, but it just could be me getting stronger.
