Since I'm playing a Human Base Jonas sixstring bass, I'm always looking for good and especially affordable strings. First time I tried these strings, I thought "man they are really tough to play" and that is a common trade in all Warwick strings I tried so far. Once you play them for a while, you will get a feeling of good control and precise articulation from your instrument, based on the strings.
Generally they add some "punch" in the mid-frequencies which could be annoying if your bass already has a tendency to boost those. If you don't like the mids, just try the sound in a band context ;-)
The Jonas is my main bass and gets played a lot - the average lifetime of the strings is around 3-4 month for me.
