28 CX-Rays will be plenty unless you're seriously loading them up, like >130kg all up. You can save a bit, add some stiff and lose very little in aeros by using DT Aero Comp. Of course, with 28H XR31s you're not exactly building aero wheels from the start, so you could just use Sapim Race or DT Comp round spokes 🙂
