I went out and bought the BIC Triumph 730R Rollerball pen. I had to try it out, but I am not too excited about the feel. This is a 0.5mm extra fine tip, which I prefer. The pen feels too light in my hand and the plastic casing, which looks cheap by the way, is a bit slippery to the grip. A pen must have a specific weight to feel right and a good grip. Although this one does describe its contoured grip area, I just cannot feel it at all.
It has a slight scratch when writing and a little more bleed through the paper than my Pilot V-ball.
It's good enough for the office but not perfect enough for my notebooks.
