I would run an SPI wheel any day, they are very nice and are readily available in a bunch of different designs. Good price too. They are tested at the World Finals and I highly doubt there were any UE rims competing. Maybe but it is not like they are supporting the hobby like SPI is.
The UE line is special to me and I will always like it no matter what. But it is just a bummer we cannot get parts so more would be willing to run their trucks all the time.
