I like mine with Schmidt easyflow 9000 replacement cartridges, they feel nicer and make good lines. That being said, my rotring 600 is what I take to the job site. For home or more extended writing I still use a fountain pen. Also the more you need to fill it the more often you can try out new color inks!
