i'm late to this thread, but i'm using tempera hybrids as well. for months now.
after reading Bozo Paradzik's words on string tension, it just seemed logical. he is a huge supporter of low tension, but specifically genssler strings.
I even spoke directly with BP about this. it all makes a lot of sense.
my personal feelings are that: metal (heavy tension, no matter the type of string) strings themselves are louder. but, low tension strings allow the instrument to be louder. you get more sound by allowing the instrument to speak. that's just the impression i've gotten, though it's logical, this is just a musicians feelings and not a scientific conclusion.
I play a lot of orchestral music during the day for my teaching job. pretty much 7am-3pm i'm bowing more or less that whole time.
but my real background is playing jazz, so i've always needed real hybrid strings.
these strings have zero compromises.
After i had them for a while, i went back to evahs, then spiros. i was absolutely stunned at how bad my bass sounded, with the stings i previously considered the best choice. What was previously a top-choice with a great result now seems choked, unnatural, bland, with less projection.
the jazz sound is warm, full sustain, and as complex as anything. the arco sound i'd describe the same. even from low to high, and even reduced my previously troublesome wolf tone to a non-issue.
i firmly believe these strings and others like them are the way of the future. I think metal (and heavy-tension synthetic) strings are just a fad for bass players that'll be gone within my lifetime.
they are well worth the money for me. i've had zero complaints, and many good things to say.
