Lite gauge stainless Lo-Riders 40-100. As has been said, the hex core makes them a little more stiff, which I really like. To me they have a growl and bite that I associate with Rotosounds without the really rough wrap wire that Roto's have.
I previously had been using the Marcus Miller Fat Beams on both my Jazz bass and Lakland 55-02, but grew a little tired of the "springy" feel of the Fat Beams when I changed from playing blues and funk to more aggressive rock with a new band. I also found that I liked the lighter gauge, especially for the B. (from 125 to 120) it gave me a more even feel across the neck than I had with the Fat-Beams.
