I built a wheel set using carbon spokes from AliExpress from the Carbon Spoke Hub factory store. I live near a ski area and haven’t have a chance to ride them extensively yet, maybe 200 miles of climbing/descending. Pretty easy to build up. I got their thinnest spokes with titanium ends and they can be laced up to standard straight pull hubs. They ship with a tool that keeps the spoke from twisting when you are tensioning. So far so good
