Actually, I haven't used this particular bridge before. I've used their others, and they worked just fine. This is just me, but sustain for bass is way over-rated. It always comes at the expense of harmonic complexity, and is the easiest thing to get electronically. I want good attack with a strong fundamental and harmonic richness. To get sustain, you (usually) add more mass somewhere in the chain (bridge, body, etc), but the price you pay (disproportionately more 2nd harmonic v first and less richness and character and usually less transient info) is too high.
Again, this is just me. I don't spend a lot of time playing long sustained notes. I DO spend most of my playing time wanting that articulate and natural attack. If I need susatin, I can get it with a compressor easy enough. Trying to get more attack from a compressor doesn't work as well, IMO.
I spent a lot of time talking with Bill Lawrence about this topic, and he agrees. He said he tried very hard to talk Rosoce beck out of that heavy bridge on his sig model, but Roscoe was convinced it had to be heavy. Bill says "You know is the best material for a bass bridge?" No, I say. "Titanium." Huh. Anybody make such a bridge? "Nope".
