I've looked at these for a couple of months now from very very close. Fonts are code and the nature of code is that it's never perfect.

@reichenstein Suggestions to consider (or, of course, ignore): Should the triangular ascender and x-height serifs be blunted to fit the baseline serifs better? Should the italic spacing be a touch tighter? Is that lovely italic Th ligature a candidate for "kill your darlings" treatment?

@celiason these are quite precisely some of the main questions of consistency I fought with, there are alternatives to each question saved in Glyphs, and the answer, so far, is no. The Th needs better spacing and the h in particular needs that daring tilt. The italic a though will see an overdue change very soon.

@celiason Triangular ascender: While it's hardly even recognizeable at reading sizes, it does give the face more character and breaks the monotony of identical serifs. Italic spacing: I don't like the usual claustrophobic italics, love the weird yet very readable Sabon spacing (it had its own technical reasons, but I nevertheless like it better). That lovely italic Th ligature: I noticed the abundance in crazy italic ligatures in the original prints and took the freedom to do more.

@celiason Also, triangular ascender: I only discovered later that it fits like a puzzle piece with the exaggerated ink traps on the iA Sans. The real reason though why it survived is that it always felt better when I brought it back. I know exactly why you said what you said. :-)

@reichenstein Of course, the other side of my "should the triangular serifs be blunter" might be "should the baseline serifs be sharper," but it sounds like you're happier with the difference.

@celiason The idea is baseline blunt but then the drop shaped terminals in a f, j, r, c sharp like the whipped cream terminals in the italics. There are similar designs out there, but then they often make the spur of a and t, and the spurs of c e sharp as well, which I find easily results in an unbalanced shape of these letters. The whipped cream italics are also not perfectly sharp for that reason. The curves just ended up looking wrong. Head serifs could take the sharpness though.
