I have the same problem! My dream is to fly fighter jets and i dont want to be stuck flying a "heavy" as you put it. I was talking to my navy science instructer and he we had a pretty debated descussion on it. The navy, though giving you a better chance to fly, has limited types of planes. The air force has many many diffrent types that the navy dosn't. And if you dont have perfect vision you need to go into the navy because your chances of getting to fly in the air force are very slim. good luck!
