We knew going into it choosing the VEX wheels that they were going to be more fragile, but with the flat field last year we had no problems with breaking them during their intended usage. If you are looking for something more durable I would look at the Andymark wheels, while considerably more expensive they are definitely more durable.
Now with the hubs on the VEX mec. wheels, our team has always ground down the nubs that are used for the versa hub system. (we just do this with a 90 deg. air grinder with some 3M abrasive pads) Then we used AM aluminum hex hubs to attach them to our drivetrain. We chose to do this because at the time vex was only making the plastic vex hubs and we wanted to use aluminum ones because of the durability.
Overall we were very pleased with the VEX mec. wheels, and even though none of the rollers did break off during the season we always had 2 spares and 2 sets of replacement rollers that can be purchased through VEX as well.
Best of luck!

For reference, the only Plastic VersaHubs are the sprocket mount ones, all live axle Versahubs (HEX and round bore) are 7075 Aluminum and always have been.
