i fly CO EWR- LAX weekly on their 752/3 with RB211s (i think COs RB2s are derated, not sure). The engineer mentioned to me that he loves working on the RB2s because it's much "cleaner" (less ducts pipes) than the PWs he worked on at DL.I believe I read somewhere here that older 74s equipped with RB2s don't have the AUTOSTART function. so, if i am eager to get in the air, i won't fly the RB2s. Plus, GE/PW has more livery options than RR. I like all three.

>Was a variant of the RB211 fitting on the A330 as well? no, some A330-200/300 are powered with the RR Trent 700 serieRB211-524 serie:B747-200B747SPB747-400B767-300L-1011 Tristar RB211-535 serie:B757-200B757-300TU-204more info here:http://www.rolls-royce.com/civil_aerospace...nes/default.jspregards, Rapha
