there are a few clubs ive played at that support that set up candies, saphire, e11even, helm bar, collectors, establishment, i think its more about your ability to set up without the engineer loosing hes shit at you i was pretty much told never to touch the back of the mixer by alll night clubs to set up serato unless the manager/promoter or engineer was there. That was untill i learnt a technique that allows you to cut your serato set up time down to about 1min and you dont need to touch the back of the mixer at all heres the video for the technique- go to 1min30 in the vid
