Glad it helped. The big part of it is that it forces one to learn to use and feel comfortable with the rudder and you can get out of it quickly.
Now, the part that it is not exactly like engine out, is that you still have power to both engines. It does help to force learning to fly in a simulated thrust differential, but you still have the power to stay in the air, which with one engine out, you might have an additional problm. Oh, well, one problem at a time. Better to practice before you REALLY need it.
Good Luck,
