Ooh, loving all the nappy chat! We're going to aim for reusable but are utterly bewildered by the selection out there and all the different options. I'm also.interested to know which give the best balance of absorbancy and bulk - DH and I are both quite slim so I keep imagining a little baby in this giant.combination of nappies, boosters and wraps!
Bumgenius seem to get good reviews? Also like Little Lamb. Our nappy library seems to have disappeared but will be in touch with the Oxford one. May use liners further down the line but will only flush after I've seen how they break up in.water. Hadn't realised how many people thought makeup/baby wipes were flushable! 
We're probably going to use naty disposables whilst we get used to having a small person. I know there isn't enough air in.our landfill for then to decompose but at least they're better than nothing. We already use their nappy sacks for the dog! Oddly it's really difficult to find degradable poo.bags but really easy to find nappy sacks (which most people then fill with non biodegradable stuff!)
We used to use Ecover but are total Method converts now. Their detergent comes in a tiny pump action bottle and is super concentrated. You then just buy refills in pouches. We find it has exemplary cleaning power, even after DH has been on DofE/CCF expeditions with the boys! We also use white vinegar for towels so imagine will do the same for nappies.
