I've read that the Double Shootouts have a relatively poor EV. This is because in most cases, the edge a player has on the second table of the DS is minimal and because most of the winners of the first SNG are better players than average and the 9 of you are competiting for only one spot.
People have suggested that playing in the main direct satellite that awards multiple seats is much better. (Eg. The Sunday 650 Main Event Qualifier on stars). One in 18 players move on. Although it costs a lot more to enter the MTT qualifier, your chances of moving on (assuming you're a good MTT player) is a lot higher than your chances of qualifying through the DS.
