I'm not a fan of coated strings, especially Elixir brand, which have an odd tone to my ears. There's something in the midrange of the wound strings that I can't quite put my finger on (I know, lousy pun). The only time I use coated strings is for extremely humid conditions during outside gigs, and then I use only D'Addario EXPs. I've tried the DR coated strings, they come in pretty colours, on a student loaner guitar, and though they're better sounding than the Elixirs, I'm still not a fan. Otherwise all I use is D'Addario phosphor bronze on acoustics and XL on electric.

Peace, Mooh.
