Reply to How important is it to know how to use the club standard CDJ setup? I'm torn

I am just about to start playing two gigs as I have a few open invitations. The reason I havent played yet is because I recently broke my VCI-100 and IMO I never thought of it a serious DJ controller. So now I am in the market for a new, higher quality, DJ setup.

At the club I will play at they use the classic CDJ-2000's & DJM-900 and the second club is more like "DJ battle" style where you bring your own gear.
Im feel like im pretty proficient in Traktor and I love the possibilities it allows but I don't like the idea of a vibe killing computer screen and a SYNC button. I believe having a comp screen between you and the crowd is like trying to have a conversation with somebody preoccupied with texting on their phone.

I've haven't had much experience with CDJ's and would like to be able to use the club CDJ setup without having to rely on traktor and my software. On the other hand, I can throw down harder in a DJ battle using traktors and an s4 or something. There are some features that I frequently use in traktor that cant be replicated with the CDJ's that are in my price range. (I already have a mixer)

So Im wondering how big of a deal is it if I can't use the standard CDJ setup if?
