Looking for feedback (spicy macaroni balls)

I'm looking for feedback on a recipe for spicy mac and cheese balls. I'm trying my best to emulate the Eureka(a chain of restaurants on the west coast) mac and cheese balls. Can I get any feedback on this work in process recipe? Any feedback is helpful. My main areas of concern are the breading, the cheeses for the mac and cheese, and the measurement.
