MyGrimm...non repro blue ROCKS! I live by it. I use non-repro blue pencils to lay out entire pages, then bring the lead in to tighten things up before the inks. As soon as you scan in B&W after inking, the blue just drops right out, and cant be seen. If you'd like to see, I can always post up a color prelim scan for you to check out. Just LMK.
Cheers!

I dont really do the color thing very well, but if someone who does feels inspired to color this up, just holla at me.
