Reply to Vestax Spin , cool adition to current SCS.3 system setup?

Right now i'm using the scs.3 system from stanton, awesome control and everything, it's also my first controller, but I really like the physic control over a mix rather than just touch it, what I mean is that I want to be able to use properly more setups than the one I got right now, for future gigs in which I can not use my own gear. Also I need something with a soundcard, so is it a good idea to purchase a Vestax Spin, map it to traktor, and use 2 "DaScratch" as effects and loops or maybe 2 decks, and leaving the scs.3 touch mixer alone or not use it at all? Tell me what you believe, and thanks in advance!
