Left handed, eh? Nice work! I see so little of this style which lets the lines do the talking. I use a 4b for everything. Softer leads usually dissappoint me, as they age harden on the shelf too quickly due to the high clay content, and wind up being more like a 2B. 4B is soft enough for darks, and hard enough to bear down on. Softer leads break too often for me. Keep your point chiseled!
