A couple of the guys have the top at the lcoal track.
My advice is always go with a car that you can setup easily and it is easy to drive. I have had no issues with the TC6 and it was very good with the kit setup out of the box on our low traction carpet. The local TOP guys have started to move away from theirs as they couldn't get it to handle as well. Saying this though, rember everyone is differet in the setup department. I just have found the TC6 easy and just like the xray, if you make a change you notice the difference.
