Actually lets make a quick calculation: An aerospoke is essentially the same as a flattened 1.5mm round spoke giving a crosssectional area of 1.767mm^2. In a rearwheel we would most likely need around 140kgf (= 1.373kN) of spoke tension in the driveside of a wheel with few spokes. That leeds to a tension of 777 MPa which is beyond the TZM's breaking point. Even if a lower spoke tension was used it would most likely fail under fatique after a short amount of time.

Obviously as a tester I don't even give any consideration to spoked rear wheels; if you're not on a disc, you're not really racing! Nonetheless, it does look like a 16-spoke front with TZM spokes would at least have very little margin between the loaded spoke tension and the UTS even without reducing the csa to exploit the extra stiffness. The search continues.
