I have to go with DR FAT BEAMS, I have them on almost everything, they turn any bass into a fat tone beaming bazooka! The only basses that don't have them are my short scale that wears GHS Bass Boomers and my acoustic that has elixirs, excluding the uke bass that has those rubberband strings. I have roundwound LaBella's on my Jazz bass and while they sound good, DR's are just plain fatter, I love those strings!
