We have Dyads on our tandem.
All my ISO590 wheels are CR18.
On a budget, consider the NoBS as well. It's the same extrusion as the Atlas, minus the stainless eyelettes and fancy finishes. Holds up every bit as well. The Synergy would be a good choice as well -- lighter than the Dyad, and a more traditional box shape, for around the same price as the Dyad.
