The XXX-S is a really good car. Its just has a different style, its more laid back. I switched to the mission because its more touchy, to where and when you need cornering and speed, its their. I was impressed when I saw the Graphite + car go, it really did handle good. I like the XXX-S in offroad (XXX-4), car is the fastest I have ever driven with a 9 turn mod. I broke a track record now me and my friend are battling for it.
Jeff- One thing to do is to switch your hub holes to the inner instead of outer (where the camber arm snaps on to the pivot ball, i forgot the name). It will make the car better, and you have more camber to adjust with too
