Your classical guitar will sounds its best with Augustine strings. A fellow player turned me on to these way back in the 80s and compared to the run of the mill brands I'd tried that were available in music stores (La Bella being one), these are leaps and bounds better. There is a warmth to the unwound strings and a nice bite to the wound ones that give a rich, full sound.
They make them in various tensions, but I've only tried the blues (regular tension treble strings, high tension bass). I would think lower tension bass might buzz too much, especially with my heavy handed style.
