I totally agree. Better for them, health-wise, to avoid over-feeding (& many pet snakes are over-fed). Not just for BPs either- when I had a large female BCI, I only fed her small or medium p/k rats except once, when I gave her a large rat & immediately regretted doing so. She was 7.5' at the time- but she was clearly uncomfortable digesting it, despite having plenty of size to do so. I don't doubt that feeding on the slim side also results in fewer meals being refused, so why waste time & money feeding larger than necessary prey? Snakes don't eat this regularly in the wild, that's for sure.
