Just shimmed mine and the change in geometry after raising the bridge has definitely improved playability, and got rid of an annoying buzz where the Low E string was vibrating against the head of the nut it passes over at the tailpiece.
Without the wiggle stick in place, the tuning seems to be stable so far, but I think I still need to prevent the bridge from rocking in its thimble — some kind of collar around the legs should sort it — anyone who's done this, what did you use and how is it working out?
