I do not like the factory hinge pin in the Encore. The used Encores you see in stores have a disturbing percentage of misfit, worn hinge pins. As a result, I chose the Omega when I shopped new.

If anyone here has an Encore that shakes, rattles or suddenly lost accuracy, then it may be time for an oversized, aftermarket replacement hinge pin.
