Does anyone have any recommendations on a spoil board cutter for surfacing the MDF spoil board on our AXYZ router? I would think it'd have to be pretty balanced, since the default spoil board surfacing program won't run at any less than 8000 RPM's. I've seen a couple of different models from Onsrud, and one from vortex tool, I'm just not sure what to go for.

Thanks in advance.
