I'm on the 400 with BA, and while not delighted with the SOP's, I've got to say that without them, I would fly one approach to a landing per month. With them, I get maybe 3 or 4 ILS's per month to go with my landing. I can't help feeling though that the heavy/deep landing thing has something to do with taking over at 1000'. You're not in tune with it like you are when you fly the whole thing from TOD.
