I have been trying out a few different brands and gauges for a long time. I know, I know, everyone does but I always went back to Blue Steels because they were perfect for me, alas they did not have a set that I wanted so I had to mix.
These strings from D'addario are nearly the same as those blue steels but with the right set.
Tone is great! The feel when sliding up and down is great! You can put these on and tune them with a Floyd and the next day they only need minor adjustment, no more stretching for weeks and retuning endlessly! Okay, a bit of exaggeration but in a nutshell, they rock!
I haven't come across a negative yet. I've been using them for about four months in rehearsal and on stage, not one broke down -and I (ab)use my Floyd to the limit-.
They stay in tune and keep the feeling of newish strings.
So, is it the end of that quest? Time will tell ....
