The string feels a bit thicker, but this is in general a good and useful feeling.
Sound is really solid, presented and really nice with a bit of dark note in it.
Fit really well with A larsen and Spirocore strings.
Last not so long in general and the first one I've got braked after two months.
There is a difference with the regural Virtuoso D, especially with the volume of the sound and the thickness.
