i'm not a huge fan of roasts but what my mom does is to throw a roast in a crock pot with some cut up spuds, and packet of onion soup mix(or 2), salt, pepper, etc, and enough water to keep it wet, and let it cook all day.

i prefer smaller cuts with a dry rub,(salt, black pepper, lots of garlic and onion, cajun, and whatever you like. it just seems easier to manage. just me though.
