There is a member here that breeds for size, jordan something, I'm sure he'll chime in. But yes, there is definitely a demand for larger ball pythons. For a lot of keepers they are a little smaller then they would prefer but still the best choice because the larger pythons are too large especially for keepers with young kids like me. Retics were always my favorite but I switched to ball pythons for my children's safely and so they can enjoy the hobby with me. I would love ball pythons even more if they had just a little more size on them.
