Burmese size/growth question

[Bogertophis]

Based on the picture I'd say it's not a burm-ball hybrid, it's a normal burm. A male could get up to and surpass 12 feet but it will take a while, they don't grow quite as fast as retics do.

Since it's chill and seems to have bonded with her - as much as snakes can - she could do a lot worse than that as a first giant python.

Well, except for the fact that she doesn't want a giant python at all. They're so appealing when small- I don't envy her decision.
