After reading so much about the Pilot Hi-Tec-C pens from various sources, I just had to go out and try one myself. Instead of one though, I went with three, in the form of the Hi-Tec-C Coleto. I never thought I would like using a multi-cartridge pen, but this Coleto is really great. I will be using this pen a bunch, and will probably try out different tip sizes, ink colors, and models of the Coleto barrel.
