Just play around with different ones you like. I tend to lean on saturated fats and monos, so check out the pasta isle and see if there are anything with those, or anything that sounds good. I don't like most oil's taste, so I aim for olive oil and virgin coconut oil (it's tasteless, you can literally put it on anything), extra virgin coconut oil smells and tastes a little like coconut.
I've heard good things about red palm oil too.
Oh, and butter!
