I don't know much about the giants either, but I have seen you mention this on several different threads. You want a burm, but you don't want him to grow quickly. Put bluntly, don't get a burm. The final adult size should be something your ready for, so the growth rate shouldn't matter much. It looks like you already have some larger snakes, so if you think your ready for a burm, maybe get some hands on experiance, then go for it. But if you want it, but you just want it to stay small, I think you might start looking at getting a different, smaller kind of snake.
