I've been working with ATBs almost 20 years now, I have always loved them in all of their natural colors/patterns.
I think we're just a few years away from the Amazons finally getting the recognition they deserve. Take a look at what has been going on in recent years...
Matt Lerer http://www.freewebs.com/amazontreeboas/ has produced some really extreme Amazons he calls "Candycanes" which appears to be genetic but to what extent is still unknown.
Danny Mendez http://www.urbanjungles.com/index.htm has proven the Tiger morph to be at least dominant, possibly co-dominant.
Danny Mendez, John Camp, & Jane Camp have proven the Leopard morph to be genetic.
Tom Burns acquired an albino Amazon a few years ago and will be proving it out very soon!
The ATB scene is so promising that even Kathy Love (the queen of corn snakes) is getting into them pretty seriously.
I think in future years as more and more things are accomplished via the Tiger, Leopard, & Amel morphs, they will take their rightful spot in the forefront of herpetoculture. I'm a hardcore ATB enthusiast...I love all of them from the $15 gardens to the $3K Tigers....I'm very happy to see this most amazing species finally sharing some of the spotlight
