I would have to say I think that breeding normal to normal is fine. I have never bred normal to normal. All of my breedings have been at least co-dom to normal. I do have some dinkers that are siblings I plan on breeding just to see if something comes out of the pairing. If they produce all normals then I guess I will have bred normal to normal...LOL
As for the general ball python community I think it is fine and has several benefits.
It would help Reduce the market dependency on imports. I know that Co-dom to normal will still produce a percentage of normals but if we were producing enough normals then why continue importing mass numbers of normals from Africa? I do know that for some profit minded people the Cost of cheap imports they can turn and wholesale compared to the higher price of Captive Bred will always be a factor.
Breeding Normal to Normal can be good breeding experience for 1st time breeders who don't want to invest in a morph/morphs to try their hands at breeding.
With Captive bred normals the possible issues with Shipping Stress, Parasites, ect. are not as much of a concern.
I do not think that completely stopping importation should happen. It would be nice to still be able to get new genetic mutations brought in from Africa. Also I would not want a general law to stop importation of farmed or wild caught animals to stop our ability to import quality Captive bred animals from other countries (Canada, European countries, ect.)
