I used to use Fender 7150ML strings. They played well for me and sound decent on a my jazz basses and my Hwy 1 P. I switched to Sunbeams and Hi-Beams since then. All I can say is the Sunbeams to my ear sounded richer and more full , better highs ,more sustain, , seem to take alot longer to break in . On my P-bass I put the 7150s back on simply because I get a better open string sound off A and E with them(deeper more flat) if that makes sense. The Fenders are a little cheaper price. And IMO sounded better on My P-Bass but not on my jazz basses
