It is no secret that I prefer Elixir over all other brands. They have incredible durability, sound amazing and the tone is preserved 'till the day they snap. This set is no different and is a great choice for 7-string. But, it isn't without it's flaws, or rather a flaw, to me at least. The 56 for the low b gets too loose with a 25,5" scale. A 59 or 60 would have been a better choice, for me at least. But I know a lot of 7-string guys who prefer a 56, and regardless this set sings. Would definitely buy again.
