Just go with what seems closely related to it. I think Liasis fuscus would be your best bet. But other possibilities are Macklott's and White Lips. And it's a stretch, but none of these are guaranteed or proven compatible, but crossing it to a Woma would be cool looking. But for all of these, definitely use a male Ringed and females of all the others. Come to think of it, you could try Antaresia too, Spotteds and Children's.
I kinda share the opinions of others, but they're not being constructive to your goals. I just wonder what they will look like. And a chance of 'not' being fugly as adults (generally speaking). And I think the Borneo x Balls are pretty cool looking, Carpondros too. And the Dicarplot wasn't too bad too. Good luck and don't get your hopes up.

>>I have been pondering the thought for awhile now whether or not it would be worthwhile to attempt to breed a ringed python with another species. I am in awe with the ringeds and would think that the banding and incredible irridescence would look incredible mixed with almost any other snake. My only dilema is I haven't been able to think of a good candidate to try this hybridization with. Any comments or suggestions would be greatly appreciated. Todd
