I've ordered AndyMark HD's as a backup in case. Backup #2 is to go with all omnis (like JVN's Blitzbuild robot but we have a CIM+MiniCIM per wheel -- shojuld be a screamer).

Joe,

Our sister team from Richmond used Vexpro mechanums last year, and broke an extremely large number of rollers off. In the end they broke so many that they put duct-tape on the things and used them as normal wheels because they were out of spares.

Now, I didn't build their robot so I can't say for certain that they had everything set up right. So I can't necessarily state that they weren't the cause of their own problems.

Are you seeing a lot of fractures at the point where the rollers meet the main body of the wheel?
