I have a rescued burm at my house right now. I personally have always loved burms but this one is testy. I had an albino male years ago that was completely kitten tame. I loved him to death. I knew a guy that had a green anaconda but this was a very unusual snake. It would take its food from your hand very slowly and gently. Id never seen anything like it. They same guy had a huge adult burm that was mean as could be. I think any big snake that has a good temperament as a baby will retain that as it gets older as long as you treat it right and handle it regularly. The choice is yours. Once you handle a couple different ones you will fall in love with one in particular and none of the others will matter
