Vex vs Andymark Omni wheels

[JesseK]

AndyMark is Aluminum, VEX is Plastic. There are big differences in the load rating.

- I read this to be 50lbs per wheel set since it is worded in terms of an entire robot which typically has 4 wheels on the ground.

Therefore it really depends on weight distribution - if the side which will carry 4 totes at once has the omni wheels, you're probably better of with the AndyMark wheels.
