So I have a full body skin that I always throw on my iPad as soon as I get one. I just recently though bought a Smartcase. It fits fine over the top of my body shield but do you guys think I should take it off as it'll stretch my case perhaps? I always use one underneath cases for the added protection but it looks like I probably don't need it, it doesn't look like dirt or anything can get in between the case and iPad causing it to scratch as it's a snug fit. Should I take it off?
