I have built 6 wheels using Dyads, including my first pair. Very easy to build and never had to touch them again. I also built a set on the A23, which were much more difficult, and have needed a fair amount of tuning up. All were 36h rear with 32h front, some with wheel smith and some with dt butted spokes.
Dyad is an excellent rim, not too wide, not too narrow, not too heavy, but solid.
