If you are using a quick release hub, do yourself a favor and get the DT Swiss RWS skewers. When using Shimano XT QR skewers we would get disk rubbing after going around corners, the RWS skewers got rid of that. In addition, when you need to reinstall a disk wheel, it is easy to re-center the brake rotor when you tighten the skewer.
