I put an adjustable stem on my road bike at the beginning and every few weeks I was able to stretch out my riding position. Had I gone with the position which was comfortable a year and a half ago, I would be nowheres near as aerodynamic as I am now and I'd hardly be able to maintain the blistering 15-16mph commute.
But where is Sheldon wrong? You even said you readjusted your stem and now found a new more aero position...couldn't this been done without an adjustable stem? Of course it could have, thus the adjustable stem is heavy and clunky as Sheldon had said.
