Regarding engine weight vs thrust, you have to be careful. There is a
difference between net thrust and net propuslive force. The RR engine may
generate a lower thrust than PW or GE, but due to its lower weight, it
delivers the same force to the airframe (think in terms of
thrust-to-weight). This is just a speculation based on what I've read
here; may have nothing to do with the actual weight question of the RR
