Reply to Ableton Push-Kontrol S2-Live Setup?

So my friend has acquired a Push just recently and I'd like to know different ways that we can utilize a Kontrol S2 on Traktor and the Push on Ableton to work together on one Macbook. I'm aware of the Midi Clock functionality but what I'm trying to get from y'all are. HOW WOULD YOU utilize both gear in a LIVE set up (gig)?
