Not sure about your wording there, airfoilmod. I'm sure GE, RR and others
all designed for the level of fuel icing anticipated/specified by Boeing.
If the GE arrangement really is better at accepting the unexpected quantities of ice dumped from the pipework, then that is luck, not design.
Two rollbacks over the entire 777 operation is a very small statistical sample. I'm not yet convinced this is only a RR problem.
