Hi again. I have been using a large original Lunette since 2007. After using some of the tips from here I eventually got used to my cup. I like it, but I think it's too big for me. Even when I fold it inside-out it tends to slide out slightly over time on my heavy days. I have looked at the size chart but I can't seem to find a shorter cup which also has the capacity of the large Lunette. Any suggestions?
