Reply to X-Session Pro crossfader - Good for scratching?

Hey, everyone. I'm getting back into VJing, and I use MsPinky's vinyl control system. I was wondering if anyone had any experience with the X-Session Pro as far as quick cuts and scratches, and whether there would be a way to assign a variable curve to the crossfader. I've read some excellent reviews of the piece on this site, but none specifically mention how well it works for "scratch DJ" style mixing. I'll be checking out some of MsPinky'd options as well for MIDI translation, but I wanted to get the ball rolling.
