Which g?

Personally, I prefer the second italic <g>.

The second one, definitely.

Most suited to accompany that roman g? Well, only italic #1 has the same kind of awkwardness.

2nd.
I will also straighten the curve on the top of the /t, I find it distracting. Or at least make it much more subtle.

I'd first try to reconcile the Roman /g a bit more with its peers before worrying about the italic. It's a charming shape, but it feels out of place to me. All other letters seem to have a more generous relation to horizontal space.

Though 4 doesn't complement the roman I think it's pretty sweet, different.  

I would say #3 looks best as a single letter, but in the whole word #2 works better. #1 seems too different to /a in my opinion.

I find both the /g and /t better integrated in the bottom sample.

The /g and /o look lighter than the /n and /r, for example, though in the case of /g it might be a deliberate measure to avoid clumping.

In both samples, the /ngra/ cluster is much more tightly spaced than /lated/. Actually, I'm wondering whether the top /g would look more harmonious if it were just spaced a little wider.

I agree with all this. Cap C also looks light. 

Yes, that's much better!

There's still the problem of the gravity well sitting somewhere around the /g/r boundary that appears to be pulling the letters close and thinning out the outer regions.

It's all rather loose.

Especially the "display" style. I think it's perfect for the "text" style, though. The problem I see is that the serifs on the "display" style are causing the loose spacing, in combinations such as /in/, /fr/, etc. Maybe they could be shortened in that style?

I think the eye on the /e could be opened up a bit more on the "text" style since it will tend to vanish at smaller sizes with the weight you've added.

The display style seems to exaggerate the imbalances of weight that I mentioned for the text style. For instance, /a feels very dark and /o/c/s very light.

I like the italics! The /j might benefit from a big more backbone.

Yes, the Roman is a big on the wide side, but I see that as a design feature. I'd file it in the Mrs Eaves category.

In your initial sample, the cursive "g"s are poorly spaced (the "gr" gap is big). I like your awkward g in the roman and I would keep the binocular structure in the italic but make it less odd, more Bembo-like.
