Pioneer DDJ-SZ vs SZ2 what are the main Differences!

Hey guys! 

So i recently just bought a DDJ-SZ-N (Limited Edition Gold # 225)

As i was messing around with it, i found out the effects dont roll over like with my sx-w. Did some research and found out that the controller is not Post Fader which killed meeeeeee.

So that kinda wants me to return it and get an sz2, but i heard that you can not use the SZ2 with vdj and other programs.

So the million questions are

1 - is there a way to fix the post fader sitruation with my Sz. 

2 - What are the differences between the SZ & SZ2.

3 - Should i keep my limited edition controller and work my away around that terrible idea of not having a post fader!
