I use these strings for D standard tuning on my acoustic, I can even go to C with them and they'll still have decent tension.
What I love is that even the plain steel strings are coated. The strings feel a bit sticky but it doesn't affect playability really.
Compared to Elixir strings, which cost 3 times more, these strings aren't that much worse. I'd record with these strings, they don't feel cheap at all.
