I don't think Lucy does special orders, especially when it comes to domes because of how much it costs her to produce a new one, it wouldn't be worth it for her in how much she'd charge, unless she charged enough to cover her overhead, which I'm afraid I wouldn't be able to pay in a lifetime. As far as rings go, seems to me that it hopefully wouldn't be as expensive to create a new one that would help in your situation, as it would probably be good for others as well. And as far as gluing the mat on, don't be afraid to glue it on to see if that will help, just use a hot glue gun. I used to use hot glue on mine when I was using foam rings, the nice thing about the hot glue is that it stays nice and smooth and won't scratch, cut, or hurt you any unlike the lesson I learned with my first set that I used super glue on, OUCH! As the foam got worn the glue ended up getting exposed, I couldn't figure out why it was hurting so bad after a while, by the time I figured it out I had done some pretty good damage to the skin around my breasts (luckily underneath) and have permanent scarring and discoloration now. But the hot glue does not do that, and unlike the super glue, which is permanent and has to be sanded smooth to reuse them, the hot glue provides a good seal, and will peel off should you choose to or need to.
Hopefully that hot glue tip will help, as I haven't found a single padding method that worked without gluing them on, unless it's got an airtight seal even if you could get them on they won't stay on for very long.
Oh, and melons brought up a good question. What size were you before you started noogling, what size are you now, how long have you been noogling, and have you used anything besides noogleberry to get to where you are? Hope you don't mind my asking, but I've been at this for 20 months now and I'm nowhere near where you are and was just wondering how long it took you and what all you used to get where you are.
