I use winter fertilizer and a spring weed/feed and never have any dandelions. The heat / drought last year killed some patches, but I've replanted grass there, though it wasn't the same type.
I currently have Fescue (pretty sure, might be Kentucky blue grass), but my old lawn was Zosia. The Zosia only looked good in the very hot weather, was brown the rest of the time and was prone to weeds, plus it needed to be thatched often to thrive. I'm glad I sold that house and don't have to deal with it anymore.
