I don't at all get the continuous mid field bombs. Surely aiming for the in goal is sometimes the better option. Especially when the guy you're kicking them to has caught the last 6 you've attempted.
Every team does it when they are 30-40 meters out from their opposition line(some more some less), because it's very hard to find space for a flat kick to land with both wingers back. Putting up that sort of bomb will usually end with the the ball being caught by a defender, but they will catch it inside their 20 with no space or momentum and under pressure. It's more about where on the field and how you want the opposition starting their set.
