I am considering a set of Velocity Aerohead built up with Ulterga hubs. My question is more about the spokes I was just going to go with standard double butted spokes, but the builder I think I may have build these up also recommended C-X ray spokes, an hundred dollar upgrade. My question is it worth it? I weight ~190 and ride between 125 to 200 miles a week with some pretty good hills. These will be my everyday wheels and I do not race. Are the X ray spoke worth the extra cake?
