The Pilot Custom 823 (amber demonstrator) is my favorite pen. I love the way it writes, the quantity of ink it holds, and that the screw down piston knob also blocks ink flow so it doesn't dry out. I have the Sailor 1911 and Pro Gear also, but prefer the Realo piston fill for the larger ink capacity. I enjoy the Rhodia paper also.
