I had been running with elixirs 12-52 on C-standard for ages, but decided to try these ones for some fatter low-end strings. These really upgraded my sound and feel when playing, it just *feels* tighter.
For years i preffered looser strings, but after a small adjustment period i now could never turn back.
I've really turned into a D'addario affiliate, and now use XL on all my instruments!
