I play a lot of faster Rock/Metal style riffs and find the strings glide well and don't tear up my fingers. They last well but obviously you should be wiping down your strings after you have used them and human sweat does differ, some people just go through strings faster than others.
I hope the video really gives you a good idea of the sound they can produce and how they can work with a clean tone or a more distorted one. I really think that if you use other brands you should give these ones a try, I truely believe that you will prefer D'Addario to your current strings.
PS. I'm pronoucing the name correctly!! :)
