I do use the self stick ones but then silicone them in place. I have a broad chest so had been concerned that using it on the L would take away from the inside diameter like it does on the XL domes. It's fine for those, but on the large I think it would kill my nipples. LOL
In all honesty, my L cups are only a back up. I press against the tops of them so I really don't see any swelling if I use them. I just liked them for a back up pair when I need to work on the XL. I guess really I should just get another set of XL for back up and experimenting on. A few weeks ago, I decided to shave down the inside foam some more and over did it, so when I pumped it tore the foam. I had to use my L's for 2 days while I put new foam on them. I also managed to break the rim off one of my L while using it. I would love to say it was from massive boobage, but it was just from the curve of my chest with too much pressure on the rims I think. LOL. All I know is it scared the crap out of me when the darn thing went. How I didn't end up cut I don't know, cause the rim came off and it just sucked the cup down harder on my chest with the broken edge digging into me!
I sometimes miss the L cups since they are so light compared to the XL, but in reality they are too small to do me any good. I just miss them sometimes and think about ways I could use them again. If they were just a bit taller I'd be set.
