My last set of new strings was a set of the new D'addarios. With them, the outer winding is coated before being wound onto the core, resulting in a more "natural" feel than Elixirs which are coated in toto.
I never liked Elixirs, both feel and sound-wise, plus the coating comes off in shreds and tatters after a while - NAPS (not a pretty sight). I've been playing the d'As for a month now and they sound fine when regular strings would be dead by now.

Cheers,
Michael
