I agree breeding what you think is pretty is likely something for which is a market as well.
I'm not so much breeding new traits I'm a sucker for eyes and whiskers though.
And I adore the Ody Rounded Fold and also the Rounded Fold that is to me just such a perfect pair of ears to snuggle

But I always like to combine them in an unexpected combination just so there aren't a gazallion of the same cats because it might be just me but I think those are harder to sell.
We can fairly assume it is a matter of time that the love shack will be filled with the Snowshoe Cream with Grotto Eyes and if everything goes well a Posh Tail, Soft Curl Ears, a Blush Shade and the latest reci whiskers.
That is if these breeders are faster than that KittyCatS! will release a new recessive and that is not very likely the case.
For example I passed the Salt & Pepper but not the Ody Bellini's I love those eyes.
I'd go for a less obvious and more cost effective way for which you don't have to obtain a trait at the highest rate and stress out to finish that ultimate recessive fast enough before others do.
It may not give you the jackpot but then the investment wasn't as high as those who have all the latest traits + the risks that go with that.
I've also noticed the love shack is a very good place to sell kitties and that live kitties sell better than boxed kitties.
