Any Ideas on What to use to stop a cover from Tearing?

In the past we have tried all sorts of things to 'blunt' the corners and sharp edges to that the cover doesn't tear. We've used plastic balls to foam. All are a pin to install

Does anyone have any cheap and useful ideas on what to use?

3 covers over 10 yrs, no rips or deterioration at all. I use foam pipe wrap over the gutter extensions and scrap pieces of Reflectix over all sharp corners, both held in place with super sticky Duct tape. Even easier though is indoor storage, as I did last winter. :W
