I would have to say for a beginner that the normal blind levels would be best. I understand why DJ is talking about with beginners not have a ton of patience, which is true, but you need to learn that as well to become a decent poker player.
For a beginner, I think that turbos are just too aggressive to get a decent grasp of how to play well... if they play too many hands, with the increasing blinds, they will be out fast as hell....if they only wait for premium, they will be blinded out by the time they have anything, and even then no one will bite.
