I would say my mixing varies, dont stick to one style. If im doing a mix what i will be sending out, i will go through loads of planning with the mixes. Making sure they sit nicely and dont sound awkward (nothing clashing), making sure they end nicely when the other tune breaks etc etc
Then there is EQing, some tunes i will mix with the bass out slightly, and then swap the basslines over when it kicks. Same with the mid really.
Agreed with the club enviroment though, you have got to do what suits, and if that means starting from the Kick & Bass it has got to be done!
