Hello all. I am not here to argue the safety of fountain pen India ink or Noodler's ink. I just wanted to share my experience.
For my line of work, I am required to use black ink, and I have found that there is a very high probability of paperwork getting water on it at some point. I started with Quink but found that it was not waterproof at all. I then switched to Noodlers X-Feather, but I found that it skips when used on "good" smooth paper.
My solution: I mixed equal parts Noodles X-feather with Higgins Fountain Pen India. I tried this for a while in a Pilot Varsity and realized it completely meets my needs. I would not have tried this first in a good pen, but at $2.50 the Pilot was a good test dummy. I am now using this (gasp) in my Parker 51 Aerometric from the 50's, and this really seems to me like the perfect black ink.
