the best way? find a static group to run leves with. Then what you do is find the highest grossing leves, do them with 4 links if possible, and fail them on the last mob. Do behests if your party members are interested. Why fail the leves? When you fail leves they stay in your journal so that they can be retried after each reset. My LS mates and I got over 40k SP each in a few hours last night doing this.
Yeah, that'll make you hit fatigue in a hurry.
