oh, that's a good one Shanti!
I never had poo-splosions after DS started on solids, not that I miss them. I think the cover/nappy combination is better for containing poos than aios or pockets. I also started using a cover over the top of sposies when we went out too, cause I think the only times we really had bad leaks was with the disposables.
(poos are breastfeeding-related anyway...)
