Love the longevity, thanks for review I will give em a try. Wish they coated 12 strings
Both D'A and Elixer have coated 12 string sets. D'A are only 10 - 47 which would be a normal "light" gauge for a 12. They clock in at 245 pound at concert tuning. I tune my twelve strings down a couple of steps so these would actually be more like 220 pounds - pretty reasonable.
I've been using Elixers on the twelves for a long time now. I like the long life and the coating seems to kill some of the jingle jangle. They make them in several gauges sets so you should be able to find what you like.
