I'm not sure i didnt see them....but, it might be tcs guys, in wich case, sorry lol but they are some of the best in the world at crawling. kinda depends on the tires though, i like panthers to be brand new for best traction since they are so soft they like to wear at fast, but like rovers and chisels i think should be broken in first, theres a good chance they were running panthers though and they prolly like em brand new too. also that course is gonna be super slick as well. cool looking course imo, i like the "tire marks" going up the main hill..
