Now depending on track surfaces you run into issues. The TLR is probably the best all around IMHO. The Xray is best on high bite and can be loosen up to run on lower bite surfaces but at the costs of Xrays high prices. I have seen people happy with their zx6 but when I look at the 13.5 class, I see TLR and Xray as the majority at big races.
