The field crew were keeping a very close eye on the diagnostics tab of our driver station (thank you!), especially during the later stages of eliminations. We've used CANbus every year since it became available and have been very happy with the results.
We have also not seen the same reliability issues with Jaguars - the worst thing that happened to us this year was a Jag on our practice bot randomly changing from id=3 to id=59 overnight. It took a few minutes to work out what the problem was but once we reset the id everything was fine. We number all of our Jags so we'll know if it ever happens again to the same one.
If anything, I'd say that we have more experience of Victors failing than of Jaguars failing, but I'd be more inclined to put that down to our team getting better at not sprinkling robot electronics with metal shavings since we last used Victors than any intrinsic reliability difference.

Using 2Can or the Serial to CAN bridge on the black jags? We tried using a 2CAN and had nothing but problems once we had some longer wire runs and more devices on the bus. In the end we scraped it and went with PWM.
