Ok, here I lowered EDGE IN DEGREES some more based on the scale I think my object is (chesspiece or statue?) and how worn the edges are. I changed WireframePro's space to Global bacause it seems "crisper" that way, but play with the Falloff options, too. I dunno, I'm just experimenting. Lastly, take down the SIZE until you are left with scetchy lines (not facet triangles). Keep going back and forth between SIZE and EDGE IN DEGREES until you have something that looks like edge-damage.
