The Uno is a true twin shape but with the inserts set back, like the SL. It looks like the Focus is a directional twin shape but no setback.
In any event, I think the Focus is supposed to be stiffer so your NXTs should be a decent match. Report back!
[EDIT: I would suggest bringing a spare pair of softer bindings, if you have them. The unfortunate part about these boards is that there isn't a lot of institutional knowledge about how they perform. On the UNO, the Salomon Chiefs with the stiff frame and highback completely over powered the UNO making transitions twitchy and unpredictable. The Fluxes have more flex all around so transitions became more gradual and predictable.]
