And part of the total package is that you can use (and get benefit out of) aero wheels with narrower tires than 37WAM, but Aksiums mask that.
That said, it's not like I think the results would be drastically different. Is ST still filled with a "narrow is aero" crowd?
In my case it was going from Grand Prix 25s to Grand Prix 28s, but I made no attempt to do same route/same speed, and I don't have a power meter. And I'm not going back to the 25s for confirmation.
