We have been doing tracks for 10 years now.
The most important thing is you power train. if you get your power just right the tracks work great.
We found out how much power a track can take. What we did was speed up the track which lowers the power. This way the robots is fast and still have great pushing and pulling power. with out ripping the tracks
Tracks are very costly but done right is very easy to drive under auto mode and very easy for the driver to control.
Last thing you need to keep your center of gravity as low as you can. this also helps out the tracks
