With a 40h Dyad, you're not likely to see any problems for a long time either way.
Excellent points, both. But if you use spokes that are 1.8mm at the ends, you should also use spoke washers so that you're sure they seat properly in the hub flange. You might just want to use DT Revolution or similar spokes (2.0/1.5/2.0mm).
