Thanks so much for your response vangarret!
Based on what you've said, I agree that a jungle would probably have more the personality I'm looking for. I will still look at everything they have at the show, but now I'm leaning more towards a JCP.
I'm hoping there will be actual breeders at this show, as opposed to the usual re-sellers.. I'm sure a breeder could give me far more info on parents' sizes, temperaments, etc. which seems to be important for both these species.
I will keep you guys updated and let you know what I come home with. There is no guarantee that there will be either species at the show, but in that case, I may wait and look for a good breeder online to order from.
