Can someone tell me if there is a difference in the capacity of the large Lunette and the large Fleurcup? According to the chart the Fleurcup holds more but I'm looking for opinions from anyone that has used both. I have a large Lunette and it fits perfectly and pops open easily. I'm thinking about trying a larger capacity cup because I feel that my flow is heavy and it would be nice to go longer without having to empty it. I see that these cups are the same size but Fleurcup holds more. Do you think it would be worth it to try the Fleurcup or isn't the capacity that much different from the Lunette? Which cup is the highest capacity available?
