Reply to Thinking of not using timecode anymore and using Traktor without CD/decks

I'm in the process of selling my 2 CDJs, to fund for a new mixer, so I will be making the switch from using timecode CDs with my CDJs.

Any help/feedback about this, how nicely does Traktor work without timecode, will I need to go and beatgrid my entire music collection in Traktor? Because when I've tried syncing before, sometimes it does't sync properly and it sets to a bar or so too fast/slow, but with my CDJS i can just jog it back into place, if I leave timecode and get rid of my CDJs, I will be un-able to do this... so just worrying a bit.

Can anyone give me some heads up about this? Anyone who has made a switch from timecode to just internal decks, or just someone who uses internal decks for Traktor.

My set up atm is
TSP2 2.6.0
Kontrol X1 (2)
MBP
Maschine

Thanks.
