I did a review of the Team Magic setup station here:

I really like mine, actually I like it a hair better than the Hudy one. BUT either one will work just fine. Most pros dont even use setup stations in offroad. Aaron Waldron and Drake use the coke can method. Set up a new coke can next to your tire, and look. Then compare to the other side. Try to make it equal. I just come from onroad so I like to know my setup is as good as I can make it....now to work on my driving... :-D
