Re: What is the best ai2 cover
We took Diaper Safari and Grovia covers on a flats-only trip with our slim (then) 14mo old. My DH and I both FAR preferred Grovia (admittedly, we often use them at home with snap-ins so we're more familiar with them). A few things I didn't care for about Diaper Safari:
-since they will fit a big baby well, it seemed like there was lots of extra fabric that needed to be wrapped around our guy's hips
-three snaps per side is too much when LO flips over and crawls away mid-change (though some may prefer having a hip snap to avoid wing droop; we don't get droop on our Grovia covers thanks to the in-line snap configuration)
-the back flap comes so low that poop got on it every time and the knit is not wipeable
-lots of exposed PUL
Grovia don't have flaps, but the mesh prevents the flat from shifting. The crotch is on the narrow side, which I like for my guy, but that means you need to make sure everything is fully "tucked in" if using a larger flat like Blueberry. I think if you were using a slightly smaller flat this wouldn't be an issue.
