Which mecanum wheels to buy?

[jbsmithtx]

Our team has used both sets. In 2013 we used the 6in Andymark ones. This year, we moved to the 4in VEXpro ones.

Frankly, the 4in VEXpro set was rushed a little bit, and they had several problems. But I have discovered all the causes of these various problems and IMHO, despite all the problems we had with VEX, I think I prefer them. They have several problems which are being resolved, but these little things are nice and are very strong. VEX personnel were much easier to work with too. They sold us replacement roller at an extremely low cost for us. THEY WANT THESE THINGS TO WORK. The andymark rollers collected carpet really bad and had a lot of sticky rollers. The VEXpro ones handled these speed much better.

But also, I haven't heard of a single team having problems with the 6in variation from VEXpro. I personally prefer the VEXpro variation, because the andymark wheels are just bulky and harder to work with IMO. Feel free to PM me any questions
