This pick the resume feature of the mark, namely that 2 sides, one side and a rhythmic solo side (angle of attack is different).
What really makes the difference (for the better) with all the picks that I used is the first good grip and the angle of attack of the media giving the impression of touching the strings.
It's been over a year that I use Niglo 4 silver, I am very happy, but the metallic side can be annoying in sound, especially in the studio when we sweep means the pick slip on the rope.
With this new model, it was really a pick ergonomic and does not color the sound, the pick now that I will use in the studio. In addition, the pick is well in hand, it is very thick and does not wear quickly (there the matter).
So for me the pick of reference even if I continue to play primarily with four Niglo money (it is attached ...).
