I have both but i dont really like the way the freestyle fits on my board, the matrix (old) has more of a gas pedal with the footbed and its mildly adjustable, but the straps suck schwanz. The freestyle binding (new) is lighter and fits my moto boots better but lacks toeside support. Im trying to decide if i should return the freestyles or just keep them. I got them for $50 and i cant stand the straps on the matrix.
