PW is all I have ever used (been lucky that they have been on bikes i have bought). I have never had this problem before, and that was all i could think of...Have 17,18 & 19t cogs and the 17t is the most worn. May just buy a new one and see if it fixes it, £45 for a new cog after 6 years is hardly the end of the world.
