we don't own ANY AIO's - i thought about the drying time, the fact we live in an area prone to crummy weather, and figured i'd need toooooo many of them to be able to use them full time and have a couple of days each to dry them. we have mostly AI2's and pockets
sounds like Pie is similar build to E, just a kilo or so lighter!
as i mentioned in your other thread, our preferences are Widdlewuns (side snappers, can be hard to get) CGR (front snap, can also be hard to get), bonnibuns (front snap pocket), trissy tots (front snap AI2), bcheeks (front snap pocket). have a few auriels and love them, but they are also very hard to get lol

do you know anyone nearby that uses cloth so you could test fit with your kidlet?

i have a strong preference for snaps over velcro closure - E undoes the velcro all the time.
