RE: 'Scoring'
No bro, you know score it? Like you'd score a piece of paper to fold it nice and straight. Dent it with a std screwdriver's edge along a straight edge enough to crease it, but not cut through it. Just enough to bend it accross the flutes. Try it on some scrap if you feel uncomfortable about messing up the wing or whatever. Do it a couple of times and it'll be a no brainer.
