For that, it would be easier to have two linear polarizers. Put a circular one in front, and it will not work. So with both types, you will always have to make sure you put them on in the correct order.

As polarizers, both types work exactly (!) the same.
So when you can find a 'sweet spot' with one, you should have no trouble finding it with the other.
