To listen to i tend to like "twin lead" guitars, bass, drums an seperate vocalist. To play in i like basically like the same thing, but i find it easier to work with rhythm/lead guitar setup, preferably with me doin lead, mainly because its what i learned and i've not got very good timing. A seperate vocalist makes life easier because the vocals can have a harmony to the tune and stuff, following a completely different rhythm to the guitars but still fitting in.
