I've managed to sell the Liquid Metal bridge pins for a small loss.

I've read other posts (on other forums) referring to their weight as "super light" or "light". They're not, they're thapproximately the same weight as brass pins and considerable heavier than ebony or bone.

They DO add sustain, as well as a little more volume. You could add that they may last a great many years without wearing. But is that worth the £150-ish it'll cost you to buy 'em?
IMHO, a waste of money.
