Thanks again Erica and Christopher! Your answers are much appreciated.
But my point is that when the pen is angled like in figure C, it is physically impossible (well, for me here, anyway!) to make a straight chisel aligned to the header/baseline because the tip of the pen is at an angle to the header/baseline!
When the pen is positioned like in figure C, the chisel is straight, yes, but at an angle. You can see that effect in this screenshot:
I put angled red lines in this Dr. Vitolo image to help demonstrate my point:

So in order to make straight chisels, seems to me I have 2 options:
1) I do like figure C, which makes angled chisels, and then touch up the letters later, or
2) I do like figure B, which makes straight chisels, but also a ragged edge on the right side of the shade.
