Light wheels may be beneficial where acceleration is more important than top speed, or where weight matters more than top speed (hill top finishes, perhaps?). But take a look at the pro peloton - aero wheels everywhere. In the racing world there has been a pretty regular weight-v-aero conversation ever since the introduction of disc wheels, and then carbon rims and trispoke-type wheels, and many many many people conclude that aero trumps weight.

However, this doesn't really necessarily apply to the B43, which I think is part of a recent "deepest V" competition that was started when HPlusSon released their rims.
