Reply to Replacing my setup: Mixer with Traktor/Audio 10 or Traktor Z2

I am replacing my entire DJ setup, getting rid of my A&H Xone : DX.
So far I am believeing about either a Xone:42 with the Traktor Audio 10 along with two Kontrol X1s and F1s, or a Traktor Kontrol Z2 along with one Kontrol X1 and two Kontrol F1s.

I know the latter would be the cheaper setup as I will be using it mainly at home, however, I would hate to carry a mixer around, if I'd have to. I believe the Audio 10 would offer a more flexible and modular setup. On the other hand Z2 is cheaper, smaller and may offer some features over the Xone:42/Audio 10.

I am playing Techno of all sorts and so far I have used the Xone : DX as a 3 deck/1 sample deck combo. The F1 looks great and I could eventually end up with 2 deck/2 remix decks.

Would like to hear your thoughts and recommendation as I have a hard time to decide what to do.
