It's elementary, my dear Watson. Actually it's an elementary aspect of economics: Supply & Demand.

At some point in the future "super fires" will saturate the market and will retail at PetCo/PetsMart for <$100. "Super-duper fires" will then be all the rage and will sell on FaunaClassifieds for >$500.

Professional reptile breeders are in a race against each other to produce colors/patterns which are rare or non-existent.

Re "looks better"... that's entirely subjective.

Re "a good snake to breed" ... for what purpose? To turn a profit? Probably yes. However, I think we should first educate ourselves more on the unintended consequences of inbreeding, genetic erosion, etc. Spider morphs, for example, exhibit a very obvious and physical flaw. How many other morphs have flaws which are less obvious and/or not physical?

The healthiest breeders are probably normals, but try turning a profit (or even breaking even) with normals.
