I have a Stronglight 1" threaded tapered roller bearing headset (1st two photos), not sure of the precise model. I found it very hard to adjust it precisely to turn lightly without any for and aft fork play. I think the problem is that whereas ball bearings offer some adjustment compliance, cylindrical bearings do not. Also, I believe that precise facing of the frame head tube is critical with these headsets as compared to conventional ball bearings. My favorite old school headset is a Specialized (last photo), which is a copy of the Campy Nuovo Record, but also has o-ring seals.
