I've been using a combination of prefolds and fitteds with my DD - prefolds with Booroi PUL covers and fleece covers, and fitteds (Cherubs Kiss Raphaels, Spunkybutts pre-fitteds, Tots Bots Bamboozles, Cute Tooshies) with Loveybums wool pull-up covers. So far I've only ever had two tiny leaks onto a wool cover, and it only takes a minute to wash and lanolise with foaming lanolin (and I'm super, super lazy LOL). Not sure about front snapping wool covers, but Sugarpeas covers are side-snapping and are fantastic. I use them with my DS.
