In our experience, the CenterTrack system works much better.

1) you can see the wear issue above with the old system,

2) the old system would skip under heavy loads for us,

3) the old system started walking off the rings on our bike.

So far, we've had none of these issues with the CenterTrack, and we can run the CenterTrack with lower belt tension, which presumably equals less drag.
