I had a Supreme B that was very noisy. I spent about 5 minutes with brace height and made it quiet. The most dramatic BH sound affect I e encountered.
IME I found D-97 FF material noisy on my Bear B riser and Bear limbs. That was many moons ago now. These days I use BCY X strings made by Chad (LBR). I also dumped the Flemish twist for endless loop strings. I use one set of cat whiskers only.
