Doing a dry run with my new cup

Hello everyone! My large Lunette ripped after an accident trying to clean the holes with a pin. I saw that the Fleurcup was on sale so I bought one since I couldn't find any being sold on mc_sales. It seems to have similar dimensions to my old cup but it's a lot softer which my vag appreciates very much. The problem is it was much harder to get it open. I tried using the 7 fold and the C fold which worked fine with the Lunette but they failed utterly with the large Fleurcup. I don't know if it is because I am not on my period or what but it absolutely refused to open up no matter what trick I tried. I was finally able to get it to pop open using the punch-down fold but I would like some advice as to easily get the Fleurcup and other soft cups like that to pop open.
