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.

I am obsessed with this pen! I bought a whole box of them (10)!!! The fine writing line is perfect for fitting a lot of information in a small space. Especially filling out forms. I used to be a business person and was very strict about using black ink. Whatever. I then switched to blue ink feeling it was more expressive. The blue/black ink gives a perfect balance of color.

This is a decent pen. I like the look and feel of the Sarasas better, and I ended up preferring their 0.5mm tip to this one's 0.38 point... it's just too fine for me. Better suited for drawing than writing in my opinion.

I've used this pen every day for over two years. I keep them in my office, in my handbag and at home. I write best with a slim bodied pen and love the blue-black ink.
