the original strings were original good, but became INCREDIBLY inconsistent, I had a LOT of low B's come unravelled, intonation was iffy on some of the A and E strings, and just a legion of problems. The new strings are MUCH better, last a long time, sound great, and are very consistent. I should disclose I am an MTD bass and string endorser, but I endorse the strings because they are awesome not just because I get a deal on them. I previously endorsed DR strings, but I like Mike's strings much better on ALL my basses, not just my MTD'S. Some of my students with Jazz basses, Ibanez', and others, they all sound better with MTD strings....the NEW MTD strings.
Just my 2¢.
