The obvious shot is a RHFH/LHBH hyzer. Don't try to park the basket, since tree kicks could be real bad. If you hyzer in a little short of the basket, it'll be fine.

Throw a putter to reach the island. If you can't pull off that shot, you should probably learn it as it'll help you out for many other types of shots.

(Both Layouts)
Because of the shape of the fairway, the it's difficult to get a lot of distance without risking something. The best line is a RHBH/LHFH that turns right and fades back toward the middle, possibly all the way out to the open. The safer line is something that fades right and stays in the fairway, and leaves you with an open line out of the woods on your second shot.

(Locomotive Layout)
With the creek on the left side of the hole, playing towards the basket is really risky until you're pretty close. Most players should probably be playing safe on their first shot or two.

(Locomotive Layout)
Oh boy is this a long hole; only the best players aren't happy with a par here. You can throw an aggressive shot off the tee, but make sure you penetrate into the woods. Unless you have the perfect drive, you'll be pretty happy to get to the corner in two. The tunnel is pretty tight after the dogleg, so throw something that flies straight, or a slight anhyzer with an overstable disc so you get some skip. The basket is out of the woods, so your upshots can be fairly aggressive as you don't need to worry quite as much about what the disc will do at the end of the flight.

(Locomotive Layout; Combines Freight 2 and 3)
Being able to see the basket is a huge advantage for your upshot, so if you want the birdie, you'll want a pretty good drive. If you're playing for par, you don't need to be super accurate on your first or second shots, as long as you get enough distance.

(Freight Train Layout)
If you're going with a RHBH/LHFH hyzer, throw it plenty high, because the basket is up a hill to the left.

(Freight Train Layout; Equivalent to Locomotive 2)
If you haven't gotten to the gap at the start of the tunnel into the woods, there's not a whole lot you can do. Don't be afraid to throw a short shot to the gap, then take a bigger shot from there.

(Freight Train Layout; Same fairway as Locomotive 15)
Don't be afraid to try to throw through the power line poles. Even if you miss your line, you have a good chance of getting through cleanly.
