Reply to Got to play around with an F1... now do I go S2 or S4?

Have been primarily a DVS user with Serato Scratch Live, 2 Turntables and a Rane 62. Have used a Traktor Kontrol X1 for some midi mapping of effects and video effects, but as of recently, I've wanted to dive into the world of controllers and after playing around with a Kontrol F1, I definitely want to go the Traktor route.

I have not had much Traktor experience, and my main reason for wanting to get into Traktor is the F1, just a whole new way to play music live, was a fun experience playing around with an F1.

I'm debating between going with a Kontrol S2 or S4. As I see it the S2 controls decks A/B and the F1 would control C/D right? What happens if you have an S4 that can control A/B and C/D?

Just want to see some opinions and suggestions on which route to take, I don't believe I can go wrong with either but am looking for some guidance jumping into the world of Traktor and the Native Instruments Kontrol series of controllers.

Thanks!
