We eat quite a lot of pasta, but nothing like proper Italians who are likely to complain if they don't get it at least once per day.

We tend to stock up on the shapes that take our fancy. On the whole, it's not so crucial exactly which shape you use, as long as it's roughly similar. For example, fettuccine and spaghetti are more or less interchangeable, although some sauces will go better on a flat ribbon than a string! Also, identical pasta from different manufacturers is often called different names.
