I think this is where the design of a lot of (most?) piers falls down. People go to all the trouble of building a fairly rigid pier, then mount their top plate on four long bolts. These four long flexy bolts then become the deciding factor for the rigidity of the whole mount.

If you do have to use a top plate mounted on bolts, these should be kept to the absolute bare minimum length possible to avoid flexure.
