I've been switching back and forth between a technical pen and a calligraphy pen lately. Both are very different in how I use them and what I can do with them. I'm finding that the calligraphy pen is faster 'cause I get the stroke width by pressure instead of artificially. With the technical pen, I normally go back and forth with the pen to increase thickness 'cause there's only so hard you can press down on one of them without destroying the nib.
