I would get the non-est to use on other boards if you switch boards for demo or trying friends boards.
the union contact or contract pro will give you almost the same feel for cheaper and better depending on your price point or the union force if you plan on doing mt. to .
Totally different theory at achieving better board flex and those Unions do not feel similar to the Missions.
That said, if you can't afford to get new bindings every time you get a new board, get the Reflex Missions.
