So pretty much no tuttos? That's good for me coz I've got quite a lot of M & L AIOs so I'm mostly looking to get a couple more of those sizes and some Smalls coz I've never bothered for a nb until now.
So not to sound dumb but what really is the difference with bittiboos? I was putting a cover over AIOs a lot anyway as 'insurance' so if boos absorb better ill probably go that way...

PS thanks for the help
