Reply to Traktor Setup for Remix Set development

Hey everyone,

I am considering investing in my own decks and controllers for the purpose, or at least under the pretense of producing remix sets for myself and others.

In case it isn't clear, I would be producing tracks from scratch but to be performed and released exclusively in the remix set format. Most or all would be intended to be used with timecode / scratching.

Here is what I am choosing between:
2x Technics 1200, Kontrol Z2, and 2x Kontrol F1 or
2x Technics 1200, Xone DB2, 2x Kontrol F1, and Kontrol X1


Do you believe that this Traktor setup would serve this purpose?
Does anyone believe that 2 decks is too limiting.

(I already have an APC, a Maschine and a Maschine mkii)
