You'll notice a huge difference switching from a skinny lightweight wheel to a heavy aero wheels.

That's true; I was always faster on Spoks than on the Mach 2CD option, although part of that was the better tyres. But that was back in the early 1990s, and I was riding time trials, not tooling around the city. There are much better wheels than Spoks available now for either task.
