Spaghettini
Less mass per strand means less sauce per mouthful, so the sauce should be light and fast. Oil, garlic, chili, lemon, clams, cherry tomatoes. Cream and ragu drown it.
Vermicelli
Treat Italian vermicelli as a slightly heavy spaghetti: clams, garlic and oil, tomato. Treat the thin export version as spaghettini and keep the sauce light.
