I don't know how LOTR is with "non-ghosting" LEDs. But with my old-style LEDs, the ghosting was horrible.
So, I installed herg's LED OCD board ($139 shipped from http://www.ledocd.com) and it's worth every penny!
Don't be put off by the .Net software or OCD application to install.
Even if you did NONE of that, the LED OCD board *alone* is enough to make a huge difference and kill the ghosts!
