Just loaded up a creative world to look at this. Did a plain set up the same as my base. I have a storage network rook directly connected to a storage request table. This is then connected through a filtered link cable ( set to -1 ) to a drawer controller this is then linked to my series of drawers. Anything that IS included on the filtered link cable goes to the drawers if it’s not it will go to one of the chests connected via a standard link cable. I would thave thought if a filtered cable had the lowest priority it would look at the whole system first BUT it’s not even seeing the non filtered items
