Best in club solution for traktor scratch

[sim667]

So I'm fed up of carting my S4 around and looking at investing in a solution in which I can use cdj's to control traktor.

So far I've narrowed it down to a few options.

1. Shut up and put up with the S4....... Its a lovely device, but a total pain in the bum to cart round festivals.

2. Buy a sound card, and use CDJ's in HID mode to control traktor, and output the sound through the sound card to the mixer - I've thought about this as one of the times I've tried to use my friends aggregated CDJ traktor set up to play live, it crashed, and we had to restart the computer mid set...... So I've been considering whether an Audio 2 is fine just to chuck in my bag to use, but I've no idea what the sound quality is....... Alternatively as I have a DJM800 I have been considering splashing out and getting an audio 10 at home, that way I can timecode my 1210's and use the S4 platters to control 2 decks too, but this seems like total overkill.

3. Aggregate CDJ's - I've got everything I need to do this, but it seems to be a bit flakey, from experience.

The thing I really want to be able to keep able to do on traktor is the phrase jumping with an X1, but as I've only got 2 usb ports on my macbook pro, Im trying to think of a work around.

Would love anyones input on which way they'd go on this

Also I should add, it would be nice to be able to use 3 decks, is that possible with 3 CDJ's and traktor?
