I use freewheels because that is what I started using and have never had a problem with them. Shimano or White Industries. Even though they are cheaper I like the Shimanos better becuase they are silent while coasting.
I have surly hubs on two wheelsets, white industries on another. I think surly hubs are a good compromise between quality and price.
If I ever kill any hubs I plan on stepping up to Phil.
