I really don't like the lower case "r" in the monospace font. It looks almost like a small capital I (the serif portion on the upper left is almost equal in size to the right section of the arc).
I like the rest of it, but the r is pretty distracting.
Agreed. The "r" looks heavier weight than the others to me. (Though I can't be sure if I'm only noticing because you mentioned.)
I definitely noticed this independently and came here--Is it normal to mix a couple serif-like characters into an otherwise sans mono font?
