I think the website is hybridhaven.com . It is run by Yasser of Spitfire.
I am not a big advocater of hybrids simply because they so often can get misrepresented when sold.
For example, if you breed a carpet to a green tree python to produce a carpondro. It is a very interesting display specimen. So why would you go back and breed it to a green tree or to a carpet to make 75%er's. That totally defeats the purpose of an extreme hybrid.
