Pilot Hi-Tec-C or Pilot G-Tec-C - what is the difference? Essentialy, nothing. Pilot has chosen to market the pen with a different name in different parts of the world for reasons I don't really know. I had used the Hi-Tec-C exclusively until JetPens started stocking the G-Tec-C, so I ordered a few to see if there was anything different between the two. At first, I thought the G-Tec-C might not have the stopping and starting problem that most Hi-Tec-C's have. Every time I would uncap it and start to write, it just flowed without any warmup time. But that faded out after about a week or so, and now I have to prime it every time I want to use it. I like these pens so much I don't mind, but it does frustrate me sometimes.
JetPens just stocks the basic black/blue/red in 0.25mm, 0.3mm, and 0.4mm tip sizes, so if you want to dive in to any of the non-standard colors, look for the Hi-Tec-C.
