Did a trial run with the Kone in the Chemex today, and I'd put it somewhere between the paper filters and a French press as far as the amount of dust/residue. Cleaner than a press but fuller bodied/thicker than a filtered pourover. I'm sure that messing with the grind can move it in either direction to some extent, I grind pretty fine but not espresso fine.
Cleanup is a cinch, just dump the grounds in the trash and rinse the Kone. Unless there starts to be buildup/discoloration or something over time it's about as easy as it gets.
At some point it just becomes fine tuning what is already on the high end of excellent compared to what is readily available and what people settle for in a cup of coffee. Fun to play with. And even if it were the biggest coffee nerd in town giving me the side-eye on the quality, I'd be well within the realm of proper behavior to backhand them.
