I have not tried Rotors, but I think these are ovalized rings, so if they are anything like my 52-42 Osymetric rings, then 54-44 would be not nearly as hard to push as it would be in a round chainring. On the "cam-like" Osymetric, the narrowest side of the chainring coincides with the "dead spot" where pedaling is weakest. I can certainly climb as easily with the 42-tooth smaller Osymetric as with the inner chainring of a 53-39 "normal" crankset...
