Hey toh, as you probably know the LC2 is made for Ableton Live so even though you could map it for Traktor im not sure how you would use it to its full capability. I havent heard about anyone using the LC2 with Traktor to be honest. If you need faders the DJ2 is a good option. Its all down to how 'you' DJ and what 'You' need from a controller. You should buy the controller that best reflects how you dj and has all the buttons/fader/rotarys 'you' need. If you dont need jog wheels then the DX2 is a winner. All i would say is that the Faderfox units are all rocksolid, well made and very responsive controllers. but the key thing is that the DX2 was made for Traktor thats why its so good at what it does.
