Gentlemen, I agree that Italians never add cheese to seafood pasta dishes, however it is true, Americans seem to love grated cheese with seafood pasta. And even with using a smaller amount of sauce with pasta, and with or without cheese, I still prefer not to salt the water. I find that cooking the pasta in the water to a very "al dente" stage, straining it and cooking the pasta with the sauce, i.e., marrying the two together, the pasta absorbes the sauce and is flavored and brought alive, as you say, by the sauce and the bit of starch left in the pasta as it cooks further. I also find that I use less sauce with this method. Honestly, to the people I know who cook and love to eat pasta, it is really a matter of personal taste. The "do salts" certainly have the decision, but you might want to try it without and see what you like best. After all, isn't that the most important thing?
