The Hi-Tec-C Coleto presented resolutions to all 3 of these problems that I noticed in the G-Tec-C. The Coleto writes without requiring scribbling, has a very comfortable grip and a sturdier body. The Hi-Tec-C refills did not require any scribbling to start and have written well every time that I used it. The violet ink is a rich purple color that is pleasing to the eye. The red ink is a bit pale for my liking, but that is not very important as I only use it for underlining things.
Once the pen starts to write the writing experience of the G-Tec-C and the Hi-Tec-C coleto refills are the same. However, the Coleto does not require any scribbling to start. The grip, body, and refills are all better than the G-Tec-C. This multi pen has definitely planted itself firmly on my list of favorite pens.
