I've been using a large classic MeLuna with a fairly high level of satisfaction for a couple years now but there are a couple of things I wouldn't mind improving on with a second cup. Here's what I'm looking for:
1) At least as much fluid capacity - wouldn't mind a little more as I'm not quite able to go a full day on my heavier days, and I hate having to change it at work. (I still haven't been able to figure out how to consistently empty it without making a mess...) Also, I don't want it to be any shorter - I have the stem on mine and it still sits pretty high. So a little more capacity and length would be great.
2) My MeLuna sometimes leaks overnight before it's full, so there's a seal issue (I have no problems playing sports or at other times during the day).
I was thinking about bumping up to an XL sport MeLuna (hopefully the extra firmness will help with the leaking and the bump in size will keep it from filling so quickly), but am wondering if anyone has suggestions for something else that might also work. I don't have the disposable income to just buy a ton of cups so want to make the best decision possible. I'm open to trying a different brand. I've looked at the size charts and am more interested in hearing other people's personal experience, especially if you've used a MeLuna and other brands.
