Is anyone else having issues with their Regulator post slipping? I'm on my second, have tried three frames, five clamps, and various greases/anti-seizes and can not keep this post from slipping side to side. All the frames and clamps I tried will hold an aluminium post at 6nm, or less, but can't hold the Regulator when tightened to more then 12nm.

Short of using carbon assembly paste, which I fear could lead to seizing, I don't know what I can do.
