Actually, when asked about two sabre fighting in the new film, Nick Gillard specifically said that it was a shame that these bits were cut from AOTC, indicating there is not much, if any, two sabre fighting in ROTS.
Incidentally, do please remember that two sabres are not endemically better than one; it is just a style thing.
