Are there any mounts out there with some fine-level, smooth adjustments? Tilt, side/side, maybe up/down? I have a PJ without lens shift, and the mount I have now is very clunky. If I need a quarter inch, its usually "THWUMP"....then way too much....its very frustrating. I've thought about installing some elevator bolts for some fine tune adjustments, but maybe there is something out there purpose built?
