My 1.1 papuans are my favorites in my collection. Both are WC. The female, however, has next to no scarring, and was imported as a neonate, which I'm hoping will improve her chances of breeding. The male was WC as a young adult.
After moving cross-country, the female went off feed for six months, which was very unusual given her normally voracious appetite. She's feeding normally now, but the earliest I think she would be ready will be 2007. She is currently about 9' and 14 lbs. The male is 10-11' and about 17 lbs.
The female struck, non-stop, for the first three weeks I had her. In the two and a half years since that time, she has struck at me zero times.
The male, whom I acquired as a fresh import, has never struck at me.
Both are incredibly responsive, incredibly "aware" animals. As other posters mentioned, they are deceptively strong, and having them out and about very quickly becomes an exercise in furniture re-arranging.
Both cruise more than other animals in my collection. The male, which had somewhat extensive minor scarring, has cleaned up very nicely in captivity, and only faint discolorations remain from most of his nicks and cuts from the wild.
Everything I have heard suggests that these animals breed at a later age than similarly sized pythons.
I can't recommend them enough. For a long time, males were more difficult to find. I'm not sure if this is still the case, as I haven't been following the market lately.
I paid $375 for the acclimated female (462 gms when I got her), and she had been in the US for about seven months at that time. In fact, she may have been hatched in Jakarta from collected eggs.
I paid $275 for the male, and when I got him, he was quite a mess. He cleaned up quickly. He had an enormous parasite load, but it was relatively easily treated. At the time I purchased them, I had been looking unsuccessfully for CB animals for about one year.
About once or twice a year CB animals do become available, but they tend to go quickly.
Again, I can't stress enough how much a joy these guys are to work with.
