Mensural c clef - metafont design/philosophy question

[Phil Holmes]

I'm playing with metafont to redesign the mensural c clef and see that most 
of the clefs are drawn by creating a pattern of the desired shape and then 
filling it.  An alternative would be to select a pen and draw the shape by 
connecting the vertices.  Is there any objection about using this as a 
method, or is it just an alternative that's perfectly OK?
