Had to come back to this.
The black worm dampener is not the one I was referring to in the first page. I use the NXG silencer/dampener, which is more like a traditional rubber dampener that just happens to cover many more strings.
The only issue with it is that it adds 5 grams, so people who are finicky about weighting might feel a difference with it on. It never comes off and it kills any and all ping. I use Kevlar mains which sound like glass shattering with no dampener, so it's a necessity.
