My team (820) and I are considering using either Tank tracks or wheels. I have a few questions for those of you who know anything at all about tank tracks.

1) what are the pros and cons of tank tracks?
-we know that we'll gain torque
-we'll be able to make it up the step
-we think we won't loose much speed

2) Can we buy premade tank tracks? If so, from where and how much?

3) How do we make tank tracks?

4) How long does it take to build the tracks

5) Any words or advice or experieces would be greatly appreciated.
