Does the conical burr grinder work better than the ceramic one for dark espresso roast beans?

Al, Actually I would say it is better to not use a dark oily bean at all . They will eventually cause problems. The Ceramic burrs are a little better but still use a bean like Lavazza Super crema to get that rich taste and it is not an oily bean.
