Reply to CDJ-400s and Traktor?

I'm sick of my SCS.3Ds and want something with traditional jogs and a pitch adjust. I'm leaning towards getting some CDJ-400s and using them as Traktor controllers. I've read a lot of old posts about some latency issues and inadequate pitch fader resolution using older versions of Traktor, but I haven't read any recent posts using the newer versions. Anyone with experience care to comment? I'm mixing house, not scratching, and I'd be using them with an X1 so I could still have a sync button when I want to use it.
