I've been a fan of the Savarez Cantiga normal tension Bass strings for a while too.
While they're not polished. I just tried the new "premium" version and they've become my favorite. I like the sound and feel of them.. They feel slightly stiffer, but not to the point of high tension. They're lasting longer for me too.
$8.99 for the bass set from SBM.

FWIW, I'm loving the Savarez Alliance high tension trebles combined with the normal tension Cantiga's. The higher tension trebles seem to have eliminated my tendency to slip the 1st string off the fretboard during longer jazz chord stretches.
