I mean the two of the best (if not the best) bass players used 66's Jaco and Entwistle; not to mention Billy Sheehan, Chris Squire, Geddy Lee,and John Paul Jones. However on the other hand just look at all the people who use Slinkys? Are these strings great because they are just that good, or their widespread-ness? How different are they from each other? WHY ARE THESE STRINGS SO WELL LIKED?
