i have 5 uluru womas and have never had a problem with any of them mind you i never go to try and touch them around food time and i always was my hands with a good soap to remove any smells when i do go to touch them. they are all perfect temperments and are definatly on par with my blackheads it would really be a toss up to choose between them.
Only 1 issue i have had is one of my adult female tried to eat the news paper that i lay her food one but that was quickly fixed and now i just use a small plate.
i have a 2yr old male tanami. i have only had him for 6months or so but he would have to be my calmest captive. not the slightest sign of stress or agression. but having said that, he has a ferocious feeding response and considers anything that moves or even sits still as potential food. because of this i always handle him with a hook and keep skin, clothes etc well away from the pointy end.
