Trying Out A New Inking Technique

I tend to really rely on Copic Multiliners to get my inking done, since I know they're Copic-safe.  Lately, I've become bored by how limited I am with Multiliners, and have been branching out, testing new inks with Copics.  This is Pilot G-Tec in a size .4, and to build up lineweight, I sketch the line several times.  This allows for an open, airy inkjob that works well with the lightness of Copics, without feeling to coloring-book.  This type of inking is more fun than slavishly using tech pens, and moves a lot faster.  The gel ink in the G-Tec is also surprisingly Copic safe, especially if you let it dry overnight.
