I typically used Elixir Nanoweb strings for my acoustic steel guitars and either D'Addario Pro Arte or Augustine Blue Label for my classical guitars. While I am a fan of the Elixir steel strings I have yet to find classical guitar strings which provide an equal "presence" from 1st to 6th, which seems to be particularly noticable on lower-priced guitars. I'd be interested to hear recommendations from experienced players so please send your comments.
