Read the CD Rainmaker review of the Stages first. It's pretty damning. He had a couple notables in the Power world assist with the science.
I waxed my chain back in the 80s. It's a hassle to wax once a week as it takes 20 minutes for the chain to heat up and the wax to flow in. But the chain stays a lot cleaner. I threw out all my chain waxing kit 10 years ago. I'm kinda wishing I'd kept it now.
