We use the standard rotation rate but I won't pull the nose up past 7 or 8 degrees until we are off the ground. We get a b1tch report if we over rotate (without hitting the tail). I don't know if I'd call it a "2 stage" rotation but to a certain degree it can be like that. I'll echo the statement that most tail strikes happen on poor landings (especially flaps 40). I am referencing the 800 only.
