I loved my TS5's so much at the track, I picked up a set of their 10 spoke wheels just for autocross.
Lots of offs at the track on the ts5, routine rumbles, even a few hits on the big big rumbles, and my wheels are straight and balanced still. I also live in Wisconsin, a state with horrible roads, so they get some rough use on the way to and from the track even.
I strongly recommend Titan 7 from my experiences. And they are several pounds lighter each than the new Z1 wheels.
