I had the challenge of playing in a band with a bagpipe player, which works best accompanied by guitar in C or F#. So I had to tune a half step up from standard 7 string tuning. And this set works great for that! since then I've moved on to baritone length 7 strings (27"), and to me that is just the right spot for tightness when playing standard B as well.
On a standard 7 string with a 25.5" scale, I would personally feel these strings are too loose for standard B.
The strings themselves are very classic Daddario quality; coloured ball ends, good tone and life, rarely breaks.
Very good quality for people that me that just want some strings on their guitar and don't want to deal with coatings, high prices and so on.
