This is basically what I wrote for the Goldo EL011's ( on-on ). I found them so good that I bought these ones, now.
They have a sturdy feel when you move it, helped by the shape of the lever ( to me, still better than the chrome ones ).
Very precise, you hear no crackling in the sound when moving it .I used the EL011's for splitting the outer coils, now I use these for splitting either the outer and the inner coils or to use the regular humbucker function.
