If I had a surly Belgian pro mechanic maintaining my bike and a team to get Silca to send the fancy high tech secret super speed waxes, it would be a nice way to sneak an extra watt or two. On my time and racing budget- its whatever the shop mechanics recommend for wet lube and leftover event t-shirt for wiping down the chain. And I lost a placing by less that a second this weekend, so I should be the demographic for this.
