Yeah... This is maybe more suited the spam section. I'm not sure you can really have a discussion on pasta shapes...
Rotini, Garden (The three colour) Rotini is the best. Plain spaghetti is alright, as well as most all the other forms of pasta. The only one I really hate, is angel hair, as the noodles are just to thin (lame), and get too sticky too fast. Whilst were on the subject of pasta, marinara (Red) sauce is the best, and it isnt right without meat (one of my sisters hates it with meat, which is insane). Thin soupy sauces are lame (like schools often serve).
