They are really neat snakes, but I can't believe how much more muscle/girth BCs have on them.
I always hear pound for pound the strongest snakes for their size are kings and BC's. BC will usually be stronger than the other giants at the same length, but they (the true giants) obviously grow and surpass everything when they hit adulthood.
