Thanks for the comments on the Laser spokes. To be honest I didnt even pay attention to the spoke sizing when I ordered. Saw CX Ray made from Laser and I grabbed the Laser.

I stepped up to the Sapim Force spokes. 2.18-1.8-2.0 butting. They will an advantage over the lasers in deformation for a given load (~30% less deformation), and according to Sapim (?) data fatigue life second to the CX-Ray. Image below is sourced from the FLO site.

If the data im finding randomly is correct, the fatigue test is ~400 lb load at 10 hz for a single spoke. My Garmin says my wheel circumference is 2124mm, or ~6.9 ft. 30 mph = 44 feet/sec, so 6.4 Hz for comparison.

I want these wheels to be pretty stout, the Laser would probably be fine, but I stepped up a bit.
