Dunlop Robert Trujillo Icon

Used recently on a 5 string ray sting. I was initially excited about the hit a little special, especially because of the tie, then the sound (except for the SI, but that is common with cordes1 5). Particularly the very crystalline grain in the mids and treble fine, as well as the rendering of snap slap. But I quickly became disillusioned: they do not take the tuning even after 2 months, worst I farted SOL, I have a lot of attack, but it was not happened to me for ages. So I go back to the good old ernie ball with his admittedly a little less pretty, but much more reliable. Shame ...
