Since U said U know how to work with CDJ`s and DJM .. I think U should stick to them .. IMHO there is no ” high end ” controller that can perform better than these ones. Try a 4x CDJ 2000 + DJM 2000 using rekordbox at home to fix your tracks and U should do just fine. U feel better using Traktor only ? It`s not a problem U can use them as controllers also.
