I'm smoking Dominican 'Cohiba' Robusto's right now... they are cheap and a pretty nice smoke... RallyJon is correct, the Cuban Cohiba's are usually pretty special... one of the perks, I guess, of living north of the 49th parallel is the availability of Cuban cigars... too bad I can't afford many of them
