I started experimenting with different gauges a while ago, and that's how I got to these here. I was especially curious about those here, because I am tall and have rather strong fingers (for an office worker), so I wanted to try out some thicker strings.
Looks and durability: The strings come in pretty shiny. Even after playing for 4 months (I have to admit that I am one of those who do not always take care of their strings after every practice session) they still look as they did back when I pulled the strings out of the package. They also did not tear for me up to this point, and don't really feel like they're up to it soon, but since this is my first try on them I can vow for that at the moment.
- Stretchability: The strings are a bit stronger, and you will feel that, compared with those for example that are standard on a new Gibson Les Paul guitar. While I feel like I have perfect control over the stretch itself while bending, after two half-notes it becomes increasingly harder to go beyond that. To be fair, I have this with "standard"-strings as well. I can feel a slight difference however, which is absolutely normal, since the strings are a bit thicker. I get a bit more tired on vibrato-intensive sessions though.
Sound: I am still experimenting here with different strings, so I do not have an opinion on that at the moment. These are also my first set strings, so it'd be unfair to compare them to the strings I have used before with respect to sound.
Resume: Very nice and incredible shiny strings, that require less care on their looks than their peers that I have tested before, and that appear to be durable up until now. I get tired on longer vibrato sessions though, so next time I'll try out the D'addario NYXL in a slimmer gauge. Nevertheless highly recommendable, especially if you already know what kind of gauge you want.
