I am trying to decide on an arboreal snake to add to my collection. I will very likely have at least one of each eventually but am unsure which to go for first. I am not overly concerned with handling them (but it would be an added bonus if I could!) and will be doing lots of research on each before I buy. (I am currently reading "The More complete Chondro")

So I want your opinion which should I go for first? I am leaning towards GTP's at the moment but that can change. If you have pictures feel free to post them and any advise/resources would be greatly appreciated.

Thanks,
