I have 6 burms and almost all over 11-12ft and have had 16ft+. I love them and honestly only you know if your ready for a big burm or not. A lot of already mentioned stuff {++props on the snake hook...its a must} One thing I have learned is that it is not a question of "if" you take a bite.... its "when". Anyone who deals with a lot of burms or retics will agree. It is just part of the hobby.
Accidents usually happen durring feeding' I have taken several shots durring feeding.
I hate to sound negative cause my true love is always these big babies, but there is some realities that you gotta face when you deal with giant snakes.
