I have a very reactive bass, and when I put the Animas on I didn't change the bridge adjusters at all--the top raised because of the lower tension and everything worked out just fine. However, now that winter temperatures have finally come to the midwest, the strings are ridiculously floppy and buzz like crazy when I use the bow (and even when I pizz) so I will be cranking them up some this week.
I actually tend to play the Animas lower than they should be anyway--when at the proper height, they sound PERFECT but are slightly more cumbersome to play than I want; when a bit lower than optimum height, they play ridiculously (absurdly, shamefully) easily but they buzz and rattle too much. When higher than "optimum height," they sound humongous and are awesome, but are a little too unwieldy to play.
They are such sweet strings, though; every time I play them, I'm thinking "Jeez! Where have these strings been all my life?" I hope Velvet never goes out of business.
