Thomastik-Infeld strings are wonderful in every way. Responsive and with a tonal clarity I just can't find anywhere else. They're also surprisingly long-lived. Even if the initial cost is higher, if you consider the great tone and durability, they're a bargain. I have light mediums on a guitar I like to flat pick and lights on my other I like to play finger-style...and they just make me a better player, period.
Great item, I mean is expensive but totally worthy. At first you should set your guitar because the tension but after that is an great update if you are tired of those bright strings, now I can feel the music whithout sound too loud. I will buy only this strings, and if you are sceptical as me at first the only thing that i can tell you is try it, is the only way to find out if something is worthy.
