I am pretty particular about who I buy from and pretty much stick to Williams wheels when not going through a sponsor. So far every set I have bought online (Hand built from Williams or S-Lite) has come straight and true. U have yet to even need to adjust any of them yet. They each have a couple thousand miles besides the newest set. Machine built wheels will ALWAYS need to be hand adjusted within a thousand miles or so and not uncommonly right out of the box.
