Now, I have close to no knowledge in super conductivity and how those puck manage to somehow stick to the rails centimeters away from the surface, but could we create some sort of directional friction? Sort of like a snowboard would work, so you could at least rely on one axis to balance yourself properly?

From what I gather, the board would apply a single linear resistance (vertical) aswell as resistance from every rotation axis. So theoretically, we enough skill, you could balance yourself on the board purely by using rotational resistance, even without the directional friction I just mentioned. You couldn't jerk your legs forward and backward, but you could push on the ball of your feet to shift backward, and push on your right foot to shift to your left.

Am I making sense?
