Which Gearbox Should I Use?

I went on VEX to look at my options for gearboxes, and now I'm stuck. I found these gearboxes online, and I think they would work well. The only problem is that I have no idea what gear reductions I should buy. Basically, I want it to be two speeds, one for driving fast, and one (more importantly) with a lot of torque to push other bots around. What's your opinion on what I should get?

And thanks in advance to anyone who posts an answer

If you want something VERY reliable, and easy to use for a WCD use this http://www.wcproducts.net/wcp-shifter-3cim/ Also.. gear ratio calculator! http://www.wcproducts.net/how-to-drivetrain/
