Same, I've been using Apica almost exclusively lately. I've been really liking the two extremes: an A7 is in my pocket, and an A4 is on my desk. It's huge, but I really like having the space for little boxes and sidebars.
Just yesterday I saw that they now have dot grid versions of their Premium CD notebooks (https://www.jetpens.com/search?q=apica+notebook+dot+grid&v=3), although not in the A4 size. I might have to make one of those my next notebook. I've also been curious about the square(ish) one, too. Not a standard size, but might be nice on a small desk.
