I've personally started with some Jungles. I'd grown up with carpets/diamonds so I figured it wouldn't be too bad.
So far I have learnt to be very patient. If you get a Jungle that is young. You will get bitten. A lot. One of mine came "100% guaranteed to bite you."
This said, I love both of them. They're great little animals, both with their own very different personalities.
I personally don't understand the excitement over womas/BHPs they hold no interest to me. I'm tempted to get a little ANT one day, as something that I can let visitors hold with out fear of it biting them (I don't want people unexperienced in getting bitten to hurt my jungles...)
If you're after a animal you can handle, you really can't go past an a childrens/spotted/stimi. While other breeds may handle well. For them its chance. A ant that hates being handled is quite uncommon.
Another thing to take into consideration is tank size/shape. I'm not experienced with womas but in my knowledge they're not all that keen on climbing and are better suited to lower tanks a lot of ground area due to their large size.
Morelia like a bit of height, depending on the individual and the exact type. I have one of my Jungles in a tall tank, that is almost completely arboreal. While the other is in a low/long tank and he sticks to the ground. I've recently tried swapping them to see what happens.
My point with tank size is to look at how much space you can afford to use. If you have a small footprinted area, (ie, not space for a long/wide tank.) then I think you should rule out a woma.
If you have some height and a decent footprint, a carpet is fine, but if you're really tight for space, you don't really have an option past getting a little ant.
I welcome any corrections on my woma related statements as I've limited knowledge with those weird pitless pythons...
EDIT: I'll pm the OP my recent youtube video of the feeding response from my Jungle.
