Sorry to bust your bubble, I use film directs ink and have very little ink clog issues and way cheaper to use than carts. Especially using 1 black cart 7 cleaning. I am in Colorado and pretty dry but I do use swamp cooler in summer. Refillable on a 4800 I think is the way to go now, but that is me. I don't think using one brand over another works for everybody. Different area different strokes.
My Opinion.
