Windage tray or not?

Is it worth even running one on a 300hp motor with a rear sump truck pan that will hardly ever see over 5000 rpm?
If I run one I would prefer a screen type first and a louvered one(such as Milodon)second.But then this is a very low buck build and I almost don't want to spend any extra money if I don't have to.

Your thoughts and opinions(or facts) please.
