I am personally breeding for bigger and healthier. As well as temperament. I have a 4,000 gram spider ball python. She’s definitely at least 5 feet long. Absolutely no wobble, sweet as can be and eats frozen thawed food like a beast. I just got my first clutch this year and already one has doubled in size and was eating frozen on the third feeding. This baby has never even tried to bite me either. I personally enjoy larger bps as generally I find them to be calmer. I could understand the smaller aspect as not everyone wants such a large snake.
