Favorite Macro Size! (Patreon)

A quick poll for all of my readers, while I'm still deciding on just *how* excessive I'll end up making the ponies in Twilight's Big Mistake. I have a rough idea of the ending, but given that compression magic will be employed to keep Twilight's house intact, there's essentially no limits to their growth... which is always a dangerous things in my hands.

So, show of hands: What's your ideal giantess size for this sort of story?
