Petal hood or round hood?

Yes, get the hood that was designed for that lens. All are different and have different lengths and widths etc... You want to one that is designed for the lens as its most efficient.

it has to be a petal so you wont see the hood when you go wide. If it is round, it has to be short and it really wont do anything.
