Daddario EXL110-7

I have been using dadario strings for a long time, the strings are nothing special, in general, out of 5 stars I put a solid 4

Great sound, my only complain is the longevity, but that's me being a perfectionist they're fine.

Not a huge Daddario fan, but these strings are good.
tension is calculated well for normal scale guitars.
only problem with them is that they are NOT made for long scale guitars and if you have a multi scale guitar, you might wanna go for something more custom.
they sound awesome but lifetime is very short. 2 shows and at least a string breaks. but! it depends on what and how you play.
in overall, if you have a standard scale 7 string and you don't drop the tuning much, its a very good option to go with.
