Ultegra - DT Swiss RR1.1 (Which version 1.1? I believe they make one with eyelets and one without eyelets. The one without eyelets are not nearly as strong and I believe is what most wheel builds use to save weight. You have better choices I think)
Ultegra - Velocity Fusion (Good choice depending on build)
Neuvation M28 Aero 3 (16F and 20R. Plus heavy at 1750g for that low of a spoke count. I would eliminate these.)
Easton EA70 (24F radial and 28R radial NDS/ 2-cross DS. I would eliminate these based on "durability")
So that gets you down to 2 choices...
Ultegra - Mavic Open Pro
and
Ultegra - Velocity Fusion
just my .02
