Thanks, Paul. I can't find any photos or videos of Sumatran x Balls or Borneo x Balls, though. The only ones I can find are of Blood x Balls. If anyone happens to know of any, please be sure to let me know. In my opinion, I would think Sumatran x Balls would look the best of the three. I think the darkness, markings and girth of the Sumatrans combined with the colors, markings and length of Balls would look pretty sweet. On the other hand, it seems like a Ball crossed with a Blood or Borneo would simply produce brown snakes...

So, let's say I crossed a Sumatran with a Fire Ball... Would the non-visual offspring be Het for Fire and if so, what percentage?

Other than being careful to not put a huge male Blood/Short Tail with a female Ball that is much smaller, does anyone see any reason why that wouldn't be safe for the female?
