I’ve found the sonic distinctions between various weights & clamps to be subtle at best. That said, over time I’ve settled on Stillpoints LPI as favorite.
The real value of a center weight comes when used in conjunction with a ring clamp to effect whole-record clamping. There’s only so much clamping you can do from JUST the label area.
Also of importance are ergonomics and thoughtful design features like: if an end groove fails, does this weight help or hurt my stlyus’ chances of survival? The thick pucks (like Stillpoints) are helpful because they’ll block the headshell / body well before a cantilever gets near a clipping edge.
I also remember an early version of Clearaudio's Twister clamp where the metal twist knob would pop off surprisingly easily; might as well have been a cartridge & record wrecking ball at that point. Wtf! Fortunately later versions fixed this.
