Don't breed champagne to champagne. The super champagne is, from what we can gather, a lethal homozygous form of the gene and anybody breeding champagne combos together should think very, very hard about the possibility of a quarter of their clutch dying in the egg. Because, if the odds are right, it's a very real possibility.
I think the breeder you bought your baby from was very irresponsible in pairing two champagnes together. Just because he/she did it and (I guess) is successful in selling their animals does not mean his practices are good or should be followed. I know that you (OP) obviously didn't know about the issues with the pairing and probably assumed it is perfectly fine considering the person you bought your animal from did it, but I guess that's just what I'm trying to warn you against. Not everyone who breeds these animals does it ethically.
I would suggest reading some of the resources posted here on this thread and elsewhere on the site, just to familiarize yourself with the genes and get a better concept of bp genetics (bc there's a lot to learn when you're interested in breeding ball morphs), and see if it's something you really want to get into. Theres a lot of responsibility involved with every aspect of owning and breeding, and that goes for any species.
Also, on a side note, I would like to mention that temperament can be hereditary. So while it may not be morph related, it can definitely be passed down from the parents as a polygenic trait. If your female champagne doesn't grow out of her skittishness and just honestly turns out to be a naturally fearful animal, you could see some of that in her offspring. Same with your Lesser's laid back attitude. So hypothetically if you bred them together most babies would be somewhere in between mom and dad's personalities.
