Out of curiosity I bought one recently and took me a day or two to figure out how it actually works
Acoustically its louder than any other pick I use. I pick some-what hard with a jazzIII but realized picking light with this pick sounds much cleaner when shreding.
Downside is if my hands start to sweat it starts to slip.
It doesn't seem to be a popular choice, wordered if any others used it before.
