FWIW, I just got the Dyads, but haven't installed them on my bike yet. They are with XT hubs and DT stainless spokes.
I'll have a report once I've ridden on them for a while. I liked the fact that they were about ~60 grams (per rim for a total of ~120 grams) lighter than the Mavics to which they are often compared.
I think I'll use them with 'gatorskins @ 700 x 28mm and perhaps with schwalbe marathons @ 700 x 35.
