I use boots disposable liners - but they go through the washing machine unless they have a poo on which then all gets flushed. This combo works for us since the end of Jan, before then we were 100% fleece users - stopped due to bum creams clogging up everything and giving me more hassle. But he does have some fleece lined nappies too, not noticed any difference tbh even overnight.
We always use a liner (even on fleece lined nappies) as it is just easier for us to clean the poo off. We also find if we are using nappies that don't have an integrated liner, that Kayleigh will get red if wet bamboo has been rubbing against her skin all day. Nursery days it is a paper liner, and fleece for home.
We really don't get on with paper liners ( we only use them with bum cream ) other wise all his nappies are fleece lined, bar about 2 or 3 which we have to put fleece in (am in the process of getting some big pieces of fleece that I can get to cover the whole nappy and roll out a bit to stop the leg casing rubbing ) he really needs the fleece, but then I know others who have had the opposite and find fleece make sore bums worse, I think it's really a case of trial and error!
Also I have some silk liners, but have yet to used them yet, I'm not to keen on the whole hand washing thing, spesh if they're covered in poo! But I guess if I use them over night they're unlikely to get pooey!
