That sounds plausible, but do you have any aerodynamic studies/tests you can point to that support this statement? I have an open mind and like to see data, but I haven't seen many tests. The 2008 Roues aerodynamic tests included the 43mm deep, 16 paired spoke, Bontrager Race X Lite Carbon Aero wheel in their tests for aerodynamic drag. It absorbed 23.4 watts of power at 50kmph. There are two other wheels in the list with close, rim depth and
16 evenly spaced spokes---the Lew Racing Pro VT-1 at 46mm deep/16 spokes, and the Tune Olympic Gold at 45mm deep/16 spokes. The power absorbed by the Lew Racing Pro VT-1 is identical to the Bontrager, at 23.4 watts, and the power absorbed by the Tune Olympic Gold is slightly higher than the Bontrager at 24.1 watts. In addition, the Tune Olympic Gold uses the same DT Aerolite spokes that the Bontrager wheel uses. So from looking at a few, data points from the Roues tests, I cannot see any demonstrable, aerodynamic penalty for paired spokes over an equal number of evenly spaced spokes. I welcome seeing more data to suggest otherwise.

Hed is putting his name on a new line of Bontrager/Hed paired spoke wheels, including the one below, and for what it is worth, (maybe worth something, maybe not), this "Aeolus" line of wheels is marketed as "aerodynamics by Hed".
