Preferred format?

Hello, everyone! I hope you are all doing well. Today I come to you with a simple question: Which is your preferred format? I know I've asked this before, and the vast majority seem to prefer the half-letter format (or any of its variants). But today I ask you with a more concrete goal: as some of you already know, I've started working on the second edition of Sacrifice. It's still several months away, so don't get too excited (I know I am, though). But I want to get ahead of things and start commissioning some art and that sort of thing that usually ends up delaying a project. So naturally, the first thing I must decide is: what size should this new book have? My initial instinct was to go for the standard 6x9 inches (a bit larger than A5, for those of us who don't understand inches) that I've been using for several of my books (most recently Ruthless Heavens, Boundless Fate), but then I thought that I would actually like this to be a bit larger. Since Alan Bahr introduced me to the seldom-used 7x10 inches format, I must say I'm in love with it. It's the size we used for Under Ashen Skies, and I think it's the perfect size for an RPG book. It's large enough to enjoy the art (and trust me, Sacrifice is going to have incredible art), but not large enough to become a PITA to use.

So here I am, asking for your opinion: Which format should I use for Sacrifice 2e? Is there a different format I should use? Please leave your thoughts in the comments section!
