Bittorrent sync

Bittorrent sync

So I am trying to figure out how to use this to best effect.

What I have is a PC and a MBP and I want to have a unified traktor collection.

I mostly use my PC for doing the tedious stuff like setting beatgrids and cue points etc. However I use my MBP for playing out mostly.

So at first I thought that I should use one way sync, but I noticed that just playing a file in traktor causes traktor to write changes to it.

So I am left wondering is two way or one way better for this?

You should really be asking this on the BitSync forums, people are still figuring out cool things you can use this awesome program for.
