As far as truggy tires go, I did a back to back on the same track, same day. I ran the renowned Proline Buckshot, Then ran the Defender-T. The track conditions would have suggested the smaller pin would be better, but I was shocked at the improvement in control, laptime and comfort when I ran the Defnder-T. If you are in the midwest racing at a track the Paintwerks crew is at, stop by and I will let you test them. If you are going to try them on your own, I would go with Yellow-X Compound.
