Francois:
Thanks for passing on your thoughts about the Preludes mon ami.
Unfortunately I have never had a good sound (for me) from any Helicore string on any bass.....from pizz light to Orchestra.
As I enter geezerhood I have decided to keep things simple using strings I can live with: Spiro Weichs/gut G on my King and Jazzer/gut or Innovation G on my Eberle.
So.....c'est tous. String experimentation has been a fascinating and expensive ride but I now prefer the satisfaction of putting 'em on and leaving 'em on
