You don't need a hood if the sun (or light source) is NOT hitting the lens at an angle. If the sun is in your frame the hood can't help you.
So, the hood is only useful when stray light enters the lens from the sides.
Personally, I find that an umbrella is the best way stop stray light. This way, you can rotate the CPL any way you like because there is no hood getting in your way. In fact, even when there is a huge amount of sun in your frame you can get around it.
I might put up an example to show you how effective an umbrella is.
