I originally used a propsaver on my SS because my buddy did on his SS, but after a few flights I decided I was better off without it. First off, I had a problem with the added speed of the brushless motor and the rubber bands - never did get a good balance between securing the prop just right or too much. Second, even as a novice pilot, I have never been in a position to crash my SS (knock on foam) due to its gentle and predictable flight characteristics.
