Reply to Traktor guy trying Serato for the 1st time at a gig... am I being stupid?

So I got offered a gig by an acquaintance who already will have Serato and control vinyl set up at the bar when I show up, he recommended that I just bring a flash drive with the tunes I want to play. Thing is, I'm used to using Traktor with a controller and have never used control vinyl.

Now, I used to spin records (although it's been a while) so I'm confident that I can beatmatch with turntables, but I'm a little worried about what the learning curve could be like. On the other hand, I really want to try it out and I don't normally get a chance to do that.

Does anyone with some relevant experience have a guess on whether or not I'll be able to play well without having tried it out before? If it's too tough I can bring my own setup and use controllers on my laptop instead.
