these are easily the best strings I have ever played. Incomparable to anything else. Allow, as you've noticed already, at least 2 weeks settling of both the strings, your bass and... your playing. Then revise the setup if needed.
Genssler advises a heavier (or, better put, denser) tailpiece for better results, but I had great results with my original (very light) one.
The singing quality is unparalleled, the range of colours equally so. Very easy on the left hand, for me you feel a good wrap of the fingers on the extra surface on these. They are extremely quick and sensitive to any input you apply on the bow, which for me is just a joy.
Downside: the sound is not recognisable particularly as that string or the other, but people
will notice a difference. It's not a standard tone at all. Because of that I wouldn't advise them (Jan-Ole doesn't either) for audition situations for example, where you might stand out even if your playing is flawless. A panel might feel something is off, without knowing really what, which is not always the situation you want to be in.
Otherwise, for any real music making, I'd hope the concept (low tension) would become standard so we get more options. I've never felt my bass resonate and project as much as it did after getting all that pressure off. It's, quite frankly, another instrument. A free one, the real voice of the bass. For me.
There's a reason Saksala plays Eudoxas now and there was a time in Berlin Phils history when they strung Solo Spirocores tuned down...
