I cant exactly answer that, I'm sure you'll get a dozen different ideas though. But my opinion of cutting when your 17 would be dont do it. Your body is still maturing right now, your still a "growing boy", and you will be for another 3 or so years. My first suggestion towards your goal is more cardio, if you dont do any now then start and you'll see results quickly. Ofcourse keep your diet in check but dont cut so young, try to continue bulking "cleanly" for the next few years. You'll do what you want anyway though so good luck.
