Not sure if this should be under critique since it is such a specific thing, but here goes....
When I was sketching this face, I really
wanted the metrics to be identical between the sans and serifed versions. I felt that would be a distinguishing feature, and handy for when a designer wanted to mix them together on a page. So far, I've developed them side by side to that end. However, I feel like I am at the point where I am playing tug-of-war trying to get them both to feel even, and not very well. The difficulty seems to be in the few letters that either don't have a serif on one or more sides (O, G, P, 2, 3, etc.) or vertical serifs (G, S, E, F, etc.)
Is keeping matching metrics worthwhile? Does it sound like a useful feature for end users? Is it even possible to pull off elegantly? If so, how might I get it to work: finer spacing, kerning pairs to the max, or another way?
Also, does the face feel too loose or too tight? Thank you all for taking a look at this.
