I think white lipped are amazing too. I don't know very much at all about moliccans, but they look awesome. Of the three I agree I'd go with the olive python.
As far as breeding goes for me, probably so. But I doubt on any large scale maybe a clutch or 2 a season, per species. But largely depends on how many different species I get. With the corns I'll probably get 2 pairs, one locale and one morph. Also with womas I'll either get a pair or trio. Gtp will be a pair or trio as well. There are several snakes I'd be happy just having as a pet and never breeding, like coachwhips, atb, red belly snakes, or garters. In the end I think I'll be happy if I have 10 females and about 6 or 7 going a year. I'm going to take some time tomorrow and write down my goals (herp and non herp) for the next 1, 5, and 10 years just to see what I feel is feasible for me.
