The PC16 I'm talking about are the black ones. That's what Farnell
has in stock currently.

By "loose feel", are you refering to play in the shaft-bushing
assembly or torque ? Either way, the black Piher PC16 didn't
strike me as particularly loose. The Spectrol 248 is what I would
call "loose" in the torque sense. I would describe the black Piher
PC16 as average in stiffness with some initial resistance as if
the wiper, when left alone for some time, started to stick to the
track.
