Reply to DDJ-SX - Traktor performance

I'm considering to buy the DDJ-SR which is coming out in a month.

But since I'm a Traktor-fanboy, I want to know how well the DDJ-SX works with the custom midimaps out there.
It might give me an idea about integration/latency/fill in the blank...?

Up to you guys, who are rocking the DDJ-SX with Traktor!
