I might point out that the stainless on the Modulus was a lower tension set but the 35" scale made them very playable. To me it always felt like the nickels were a tauter string yet on a shorter scale, not vice versa, but that may be just my imagination.
For whatever it's worth I always thought that rounds of either type sounded better on Jazz Basses or Jazz Style Basses and flats better on PBasses but that just my taste. Your ears may tell you something different.
