I like the Duratrax Shotgun / Louise Maglev tire. Very smooth and easy driving tire that doesn't catch ruts very much on a rough track. I like it where Calibers would be used.
Our pre mounts (all original older wheels and foam style) tend to have about one sidewall tear per four. Juts seems to be a bit of a weak spot in all the high speed, banked corners that we have. The performance of the tires itself are excellent though, especially since they are sold at only 2/3rds of the price of aka/proline/JC.
My only wish is that they had a Bowtie / IBeam styled tire.
