Comic Book Pencils

I have these old "graphitstifte" (graphite?) Pencils that I use now, 5B-5H. But I'm going to need a new series soon and I think I would like a dark line. Has anyone tried the Graphitint Derwent? In addition, this type of paper? Right now I'm using "average weight, light texture" sketch paper, but wonder if there is something better for the kind of drawings I make. It is produced mainly comic and game characters / enviro design type stuff that I want to scan into a computer later.

we pencils with no eraser, but do you have a gum Sher who do not leave marks
