Based on what I know can get through a large screen like that, I would advocate using a larger cone of finer hardware mesh to deliver same results with better protection against fod. My silicon numbers are same as your levels(good i think). Pratts philosophy is no hardware in the engine compartment that could get through the inlet screen. That screen could suck my Buick in.
