i think DR Low riders are awesome... expensive yes but worth it... hex core for extra stiffness.. you can get a real low action on these,.. an amazing precise tone on a jazz bass
i do prefer the round core strings though, for a bit of floppy growl on a jazz bass.. MM's are my string of choice...i dont want to sound like Marcus Miller but they feel great to play, and they have a great bottom end to them... i will probably never buy another brand of string...
