Hello to all of the FPN I only used lamy inks and I'm interested in trying out new inks and I saw some that caught my attention because of their beautiful colors like noodler's walnut, bad blue heron, the Lawrence and any other black ink. I have also heard that some are resistant to the passage of time, water etc.So I ask you what do you think about these inks?I use a lamy 2000 BB modified to stub
