Reply to Venues around LA

I just bought a pair of 1200s (I'm used to using them from before the days DVS existed). I haven't done this for a really long time but just planning on getting back into it, and starting with some smallish venues/clubs around downtown LA.. Most places I see some sort of serato system installed.. two 1200s and a TT57-SL or some other mixer and the serato boxes.

I'm NOT wanting to get into a features debate over which system is better etc, I'm just wondering what I can count on being able to do. Say I get a Z2, is that something I can bring with me to any venue and connect with their house decks, etc? Or will some venues insist that I bring my own laptop with SSL on it? Since I'm just getting this going, I'd rather figure out what I need to do on SSL if I'm going to be in a situation where that's what I'm forced to use. On the other hand, if it really doesn't matter and one can bring in whatever is necessary, then I'll probably want to go the Traktor route..

So.. this is primarily a question of club "standards" for the LA area.. anybody have any personal experience with this, or insight?

Thanks
