Kinlin xr22rt or the 26rt are good choices. The mavic open pro ust should be fine but is not asymmetric.
I suppose you could spend more on the pacenti forza. It's not better though.
Avoid any shallow wide rim in lower spoke counts unless your doing a 32 spoke build. Shallow rims can twist and the spoke count helps stop that and keeps them stable. Also shallow rims lack radial stiffness and the spokes add that. That's why thicker spokes with shallow rims are essential for a rear wheel.
