Best treads to buy?

Hey, I noticed recently that I can't build a tank, soley for the reason that I have no treads. Which is the best treads to buy for a tank?

Lego Technic link 3711 (for one and two stud wide treads system) and 3873, my opinion. For most of my tanks I used these, with a good suspension system they run smooth and with very little friction.
