I don't think there is a material difference between the ink output of the RT/DX
lines. Other than the obvious ink capacity of each refill, I prefer the
retractability, grip and design in general of the RT. Definitely one of my
favourite gel pens - it writes a lot better on 'normal' paper than the Hi-Tec-C
line, although I still prefer Hi-Tec-C 0.3mm tips if I have better quality
notebooks to use.
