Sounds like you’re about to shoot yourself in the foot :) I really wouldn’t subclass here. If is_important can change, that’s a bad idea. It sounds like a mutable attribute.
You can set up a method on your article EO called importantPDFs() and use that as a propertyKey in your rules. Since it isn’t a real relationship, you’ll need to manually set up the things that are set automatically by D2W when EORelationship info is available. Stuff like componentName, keyWhenRelationship, etc.
To answer your question about why the result is duplicated… you’d need to fs.setIsDeep(false) [default true] or fs.setUsesDistinct(true) [default false] on your EOFetchspecification.
