sounds like a lot of work to avoid the flip. i can execute that alg in about 4
or 5 seconds, and its not really all that common of an ending. i find if i do
see it happen or that its going to happen when i get to the last couple of
edges, i might try this move which flips 2 middle centers at FL and FR. E' F U
F' L F' L' F E (number 4 on http://bigcubes.com/5x5x5/lastedges.html is the
mirror of this and will also work, i've found its easier for me to do it on the
left side instead of the right)
i think there are other endings that are crappier and take more time than the
centerflip one, at least for me. to avoid this completely check out the cage
method (Per knows this method well) for solving its, it fixes the edges before
all the centers, like how mike said. hope this helps.

Or you can re-order your solution so that the error is "caught" early
and can be fixed using intuitive sequences. Just match up the
edges /before/ you do the centres -- or (perhaps better) just after
you've done the U and D centres. But I don't know whether that's
feasible in solution meant for speed.
