I'm just a little bit biased here as I have an awesome black and gold Jungle, so I'd say Black and gold. I got it as my first snake and she was the stereotypical Jungle in that she bit everything and everyone, air strikes, strikes at the front of the enclosure. I'd average about 10 tags every time I handled her. She's a pussy cat now and absolutely gorgeous to boot.
Colourwise, if you have a good breeder like we do up here in Darwin, go out have a look at the Sire and the Dam and have a handle of a couple of different hatchies and see which one handles best and don't decide on male or female without handling a few. They will be fairly dull to look at in the beggining but will develop their colour over time. Just keep in mind that the Albino Darwins you see that are white and yellow/orange don't start out like that, They're an all over orange colour, my yearling is just getting her colours now. My Jungle certainly didn't look like she does now.
If you get a Jungle my only advice is not to lose your nerve and get frightened of handling it, they will sense that and it helps to heighten they're senses and put them on edge with snapping the usual result. There's no doubt that the amount of handling all my snakes get would be deemed as overhandling by a lot of other owners, I make no apologies for that as I see the outcome every day I get my critters out. The only time they are not handled is after feeding and then it's 48 hrs before I get them out again.
Enjoy your Jungle mate, they're awesome. Put up some pics when you get it.
Cheers,
Ned
