Has anyone ever practiced iaido? What do you think of it?

I'm asking because I think it would be nice to train iaido along the kung fu. With kung fu I train my body and with iaido, mastery of the sword

In case you didn't know, iaido is a kind of japanese swordsplay, "the art of drawing your sword from the scabbard". In higher levels of training you use real katanas instead of bokken.
