personnally i prefer the aio's, they sit better on P and never leak. i may have to cchange them slightly sooner but that doesn't bother me as i tend to use the ittis as round the house nappies,
if you're after the tiger then i'd take whatever yyou can get your hands on as its a ltd edition and won't come up much.
also, itti are releasing a new design on sunday 11am uk time, theres a sneak peak on their fb page but general consensus is that its a OSFA.
