R10 : Great sound but prone to breakage

I love the sound of these strings. They start out pretty bright and zingy but they soon mellow out to a very nice, mid focused tone.

My only complaint is that they seem to be made from more brittle steel than most other strings. They do NOT like to be loosened (like for a setup) and then brought back up to tension. I often experience breakage in situations like that. I guess that's why Rotosound provide an extra high E-string.

I've actually experienced the same with Rotosound BASS stings which strongly suggests that Rotosound use a more brittle type of steel than other string manufacturers. I mean, bass strings should be able to handle being loosened and brought up to tension. With Rotos they often break.

Still, the tone is great and they're cheap. I'll definitely keep using them, at least on SOME of my guitars.
