Kontrol X1 mk 2 + Z1 set up

Hi All.

I am in the market for a new gear set-up as my Novation Twitch was recently stolen.

I am currently looking at getting a Native Instruments Kontrol X1 mk 2 to run alongside a Z1 (and hopefully a F1 at a later stage) and was wondering if there's anybody out there who's using the same set up and can comment on the functionality, reliability and overall performance of this combination of controllers.

Also if you have been experiencing any problems with these units either by themselves or in combination with one another please let me know.

Thanks for the help!
